When burger is mostly browned, add onions and saute. Continue cooking until onions are soft and meat is cooked through. If you have any grease from the burger, strain off. Remove from heat.
½ cup onions
Add tomato sauce and taco seasoning.
2 tablespoons taco seasoning, ½ cup tomato sauce
Strain pinto beans, removing any liquid and add to pan. Smash some of the beans while mixing in.
1 15 ounce can pinto beans
Allow mixture to cool, just slightly and then add cheese and freshly chopped cilantro.
1 cup Mexican blend shredded cheese, ¼ cup cilantro
Place about ½ cup of filling on a tortilla. Fold up bottom of tortilla over the filling.
8 flour tortillas
Fold in each side and roll tortilla forward creating a little packet. Place on a baking sheet lined with parchment paper with the seam side down.
Repeat with remaining tortillas
Place ½- 1 inch of oil in a heavy skillet and heat over medium heat until temperature reaches 365°F - 370°F.
Use tongs to carefully place one filled tortilla in the pan. Hold chimichanga with tongs to prevent tortilla from unrolling. Toothpicks can also be inserted in uncooked chimichangas to hold tortillas in place. Cook all sides until golden.
Place cooked chimichanga on a baking tray lined with a rack and place in a 300°F oven.
Continue cooking remaining chimichangas.
Leave cooked chimichangas in oven for at least 10 minutes or until they are heated through.
Serve hot with sour cream, salsa, guacamole and freshly chopped tomatoes and onions.
Notes
The amount of oil used will vary depending on the size of your pan. You want a ½ inch to 1 inch of oil in your pan.
Monitor the temperature of your oil and keep it between 365-370°F.
The chimichangas want to unfold when placed in the hot oil. In order to keep their shape either place two toothpicks in the chimichangas before frying or hold the chimis in place with a pair of tongs while cooking.
Cook just 1-2 chimichangas at a time.
Keep your fried chimichangas on a baking rack in a 300°F oven. This helps keep the tortilla crispy, but also makes certain the internal temperature of the filling becomes hot (165°F).
