Mix chicken, beans and salsa mixture in large bowl.
Heat 10 tortillas in microwave until soft and pliable.
Put one tortilla on a plate, put ¼ cup of the chicken/bean mixture on tortilla, about an inch from one edge. Roll one turn, fold edges in, and keep rolling to the other side. Place in 9x13 pan.
10 chimichangas fit in a 9x13 pan.
Brush tops with oil.
Bake at 400 degrees for 20-25 minutes until golden brown.
Serve with shredded lettuce, cheese, green onions, sour cream and salsa.
Pans of chimichangas can be frozen before baking. Do not brush with oil until ready to bake.
Alternately, you can bake all the chiimichangas (brush with oil first.) Let them cool, then wrap each one separately in waxed paper, put 10 or so in a gallon zip lock bag and freeze. These make great lunches! Microwave for approximately one minute.
