When you're ready to make the burritos preheat oven to 375 degrees F (190 C). Fill each burrito with the scramble, yogurt, cheese, avocado, salsa, peppers, and spinach or lettuce. (Feel free to adapt this to your taste). Wrap them up tightly and wrap in foil, then put them in the oven to heat for 10-20 minutes until as hot as you'd like (I'm the type that likes my food really hot so just adjust this to your preference or if you like things more lukewarm just serve them immediately and skip the oven.)
