In a medium nonstick skillet, crumble and cook the sausage until thoroughly cooked; stirring frequently.
Add the bell pepper and onion to the sausage. Cook for 1 minute and drain the sausage. Remove the mixture from the skillet; keep warm. Wipe out the skillet with a paper towel.
In a medium bowl, whisk together the eggs and milk. Pour the egg mixture into the skillet. Cook the mixture until it is set but still moist, stirring occasionally.
Divide the sausage mixture evenly among the tortillas. Top each with a fourth of the eggs. Spoon the sour cream over eggs.
Roll up to enclose the filling. Top each burrito with your favorite Pico de Gallo and serve.
