Preheat oven to 400°F.

In a skillet, cook sausage over medium heat until browned. Set aside.

On a large sheet pan, toss onions and bell peppers with olive oil, salt, and pepper. Roast for 10 minutes.

Whisk eggs, cottage cheese, and milk in a bowl and pour over veggies. Sprinkle with salt, pepper, and cheese. Bake 10–12 minutes until eggs are just set.

Remove sheet pan, divide egg mixture and sausage into tortillas, fold in half, and secure with toothpicks if needed.

Lightly brush outsides with olive oil or butter. Return to oven and bake 10–12 minutes, flipping halfway, until golden and crisp.

Remove toothpicks. Top with Greek yogurt, cilantro, and salsa. Serve warm!
