Method
Make the Eggs
Start by preparing the eggs. Crack all four eggs into a medium-sized mixing bowl. Add the 1/4 cup of low-fat cottage cheese along with a good pinch of salt and a bit of freshly ground black pepper. Use a whisk or fork to beat the mixture until the eggs and cottage cheese are well combined and slightly frothy. This will make your scrambled eggs extra creamy and flavorful. Heat a small amount of oil in a non-stick skillet over medium heat. Once the skillet is warm, pour in the egg mixture. Let it sit for a few seconds, then gently stir with a spatula, moving the eggs from the edges to the center as they begin to set. Continue to cook until the eggs are just done soft, fluffy, and slightly moist. Remove the scrambled eggs from the skillet and set them aside.
Warm the Beef
Using the same skillet (no need to wash it hello, extra flavor!), add your leftover beef roast. If it’s been in the fridge, it’ll need a couple of minutes to heat through. Keep the heat on low to medium and stir the beef occasionally so it doesn’t dry out or burn. You’re not trying to cook the beef again, just warm it up and bring back its tenderness. Once heated, turn off the heat and set the beef aside.
Build the Quesadillas
Lay one tortilla flat on a clean surface like a cutting board or countertop. On one half of the tortilla, sprinkle 2 tablespoons of shredded Colby Jack cheese. Next, layer on half of the scrambled eggs, followed by 1/3 cup of the warmed shredded beef. Finish the layering with another 2 tablespoons of shredded cheese on top. The cheese on both the bottom and top helps everything stick together when it melts. Fold the tortilla in half over the filling, gently pressing it down so it holds its shape. Repeat the process with the second tortilla and the remaining ingredients.
Cook the Quesadillas
Before cooking, wipe down your skillet if there are any leftover bits, then add a small drizzle of oil. Heat the skillet over low to medium-low heat. Carefully place one quesadilla into the skillet and cook it for 2–3 minutes on one side, or until the bottom is golden brown and crispy. Flip it carefully using a spatula, and cook the other side for another 2–3 minutes. You want the cheese inside to be melted and gooey, and the tortilla to be crisp but not burnt. Repeat with the second quesadilla. If needed, add a bit more oil to the skillet between batches.
Serve and Enjoy
Once both quesadillas are cooked, transfer them to a cutting board. Let them sit for about a minute (this helps the cheese set just enough so it doesn’t spill out). Slice each quesadilla in half or quarters using a sharp knife or pizza cutter. Serve them warm with your favorite sides like salsa, sour cream, or guacamole for the perfect comforting meal!

2 Mission Carb Balance flour tortillas
4 eggs
1/4 cup low-fat cottage cheese
2/3 cup leftover beef roast (or any shredded beef)
8 tablespoons shredded Colby Jack cheese
Salt & pepper to taste
Oil for cooking
Directions
- Make the Eggs
First, crack your eggs into a bowl. Add the cottage cheese, a pinch of salt, and some pepper. Whisk it all up really well. Heat a little oil in your skillet and scramble the eggs until they’re just cooked. Take them out and set aside. - Warm the Beef
In the same skillet, toss in your shredded beef and warm it up for a few minutes. No need to overcook it just needs to be heated through. - Build the Quesadillas
Lay one tortilla flat. On just half of it, sprinkle 2 tablespoons of cheese, then add half the eggs, 1/3 cup beef, and finish with 2 more tablespoons of cheese. Fold the tortilla in half over the filling. Do the same with the second tortilla. - Cook the Quesadillas
Wipe out your skillet if needed, add a little oil, and cook each quesadilla on low heat for a few minutes on each side. You want the outside golden and crispy, and the cheese inside melted and ooey-gooey. - Serve and Enjoy!
Cut each quesadilla into halves or quarters and enjoy with your favorite salsa, sour cream, or even some guacamole.
Notes
- Don’t overcook the eggs! You want them soft and fluffy not dry.
- Keep the heat low when cooking the quesadilla so the tortilla doesn’t burn before the cheese melts.
- Spread the filling evenly so the quesadilla doesn’t fall apart when you flip it.
- Press gently after folding, don’t smash it flat!




Serving Suggestions
- Add a spoonful of salsa or pico de gallo on top.
- Serve with a side of sliced avocado or guacamole.
- A dollop of Greek yogurt or sour cream makes it extra creamy.
- Want some crunch? Serve with a small salad or tortilla chips on the side.
