California Avocado Breakfast Burrito

Wrap tortillas in foil; warm in a 400 degree F oven.
While the tortillas heat, saute bell pepper and onion in butter until soft, about 5 minutes.
Meanwhile beat together eggs and salt.
When vegetables are done, pour egg into pan; gently stir in avocado.
Cook, over medium-low heat, stirring constantly, until soft curds form, about 3 minutes.
Put 1/4 of the egg mixture down the center of one warmed tortilla; sprinkle with 2 tablespoons cheese.
Fold in top and bottom of each tortilla.
Roll up from side.
Repeat with each tortilla.
Garnish each burrito with a dollop of sour cream and a spoonful of salsa.
