Preheat oven to 425 degrees Fahrenheit and line a baking sheet with foil.
Brown the ½ pound sausage in a large skillet over medium heat. When sausage is almost cooked through, add the 2 cups chopped spinach and ⅓ cup diced green bell pepper and saute for a few minutes.
Crack 6 large eggs into a bowl, whisk, and add to the skillet. Stir occasionally until eggs are just barely cooked through. Remove from heat and stir in the 2 tablespoons crumbled feta cheese.
Microwave the 7 medium tortillas, for 30 seconds or until pliable. Divide the filling between tortillas. Top each with a little of the ½ cup shredded cheddar cheese and the ½ cup salsa,
Roll each filled tortilla up tightly and place, seam-side down, on the baking sheet. Spray the tops of taquitos lightly with cooking spray and sprinkle with a little kosher salt. Bake for 10-15 minutes or until crispy. Serve with extra salsa for dipping.
