Once heated, add onion and peppers and cook on medium high heat until softened and a little charred, about 10 minutes. Set aside.
On an extra large tortilla, set down a line of rice, then layer on chicken and veggies. Add any other optional ingredients, being careful not to overfill.
Begin rolling your burrito, making sure to tuck the sides in as you go.
Once the burrito is rolled, place it seal side down in the still heated pan and cook on medium heat, turning a bit every minute or so to add crispness.
