Slow Cooker Beef and Bean Burritos

Okay, so I have been posting a lot of slow cooker recipes. They are perfect for the summer though. Who wants to use the oven when it's 109 outside, really? Actually, I make this recipe ALL the time. It's really good. Beans are not necessary.

Slow Cooker Beef and Bean Burritos

1 (2-pound) London broil
1 (1.25-ounce) package taco seasoning mix
Cooking spray
1 cup chopped onion
1 tablespoon white vinegar
1 (4.5-ounce) can chopped green chiles
1 (16-ounce) can fat-free refried beans
12 (8-inch) fat-free flour tortillas
1 1/2 cups (6 ounces) shredded Monterey Jack cheese
1 1/2 cups chopped plum tomato
3/4 cup fat-free sour cream

Trim fat from meat; rub seasoning mix over both sides of meat. Place meat in an electric slow cooker coated with cooking spray; add onion, vinegar, and green chiles. Cover with lid; cook on low-heat setting for 9 hours. Remove meat from slow cooker, reserving cooking liquid; shred meat with two forks. Combine meat and reserved cooking liquid; stir well.

Warm beans and tortillas according to package directions. Spread 2 tablespoons beans down the center of each tortilla. Spoon a heaping 1/3 cup meat mixture on top of beans. Top each with 2 tablespoons cheese, 2 tablespoons tomato, and 1 tablespoon sour cream; roll up.
