On broil until skins are blackened about 8-10 minutes. Set aside in a bowl and cover with a lid for 10 minutes. Then peel off skins, remove seeds and chop the peppers.
Cook the beef
In a large skillet, cook until browned and cooked through, about 8-10 minutes.
Heat up the tortillas
In a pan or microwave, to make them become pliable then add shredded cheese, avocado, salsa, peppers and beef in the center of tortilla.
Fold your burrito
Be mindful not to overfill, as this can make folding difficult and can cause the tortilla to tear. As you fold, press the filling gently but firmly to compact it and make the burrito easier to handle.
Return to skillet
To make burrito crisp up and hold together better.
