Preheat oven to 350 degrees F.
In a large skillet, cook turkey sausage, breaking it up as it cooks, until it is cooked through.
Remove sausage from the pan.
Add olive oil to the pan and heat over medium-high heat.
Add onion and bell peppers, and cook until softened, about 7 minutes.
Add corn, black beans, chili powder, cumin, and salt, and stir well to combine.
Cook another 3-5 minutes, until everything is combined and warmed through.
In a medium bowl, whisk together eggs and milk, and season with a dash of salt and pepper.
In separate skillet, heat butter over medium heat.
Add egg mixture, and cook, stirring occasionally, until eggs are scrambled.
To assemble, place about ¼ cup of eggs, ¼ cup of sausage, ¼ cup of vegetable mixture, 2 tablespoons of cheese in each burrito.
Roll the tortilla once, then fold in the edges, and finish rolling the burrito.
If you are planning to eat them right away, place them on a baking sheet.
Bake in preheated oven for 5-7 minutes, until cheese is melted.
If you are going to freeze them, wrap them tightly in foil or plastic wrap, then store them together in a large plastic bag.
After frozen, unwrap from foil or plastic wrap, wrap in a paper towel, then microwave for 2 minutes, flip over and microwave another 1-2 minutes, until warmed through and cheese is melted.
Top with Greek yogurt, salsa, green onions, and/or cilantro.
