For Chimichanga:
Spicy ground beef
Fajita size flour tortillas( one pack)
Veggie oil 
Toothpicks 
Optional:
Mexican rice
Beans
Cheese
Veggies
Lay down tortilla and put in the middle about 2 tbsp of beef. Top with rice, beans etc. just about a tablespoon each so you can wrap the Chimichanga. Fold the sides in, the bottom over the sides and then roll so the seam is at the bottom. Secure the seam with a toothpick. Heat up veggie oil in a heavy skillet( about 1/2 inch high). Once almost smoking add chimichanga seam side down. Fry for about 2 minutes till brown and flip to do the other side also for about 2 minutes. Remove and place on paper towels. Once slightly cooled remove toothpicks and serve. *use this spice mix with leftover pork or chicken too
