Brown the ground beef with a little garlic (and onion if you like.) Drain off any fat.
Blend the salsa to remove chunks if you have picky eaters. Place a little salsa in the bottom of your slow cooker, then stir the rest into your ground beef.
Then chop up your olives into dices. We used a Handy Chopper.
Place a small amount of refried beans, olives, and cheese on the edge of a tortilla. Roll up and place seam side down in the bottom of your slow cooker. Repeat for the remaining tortillas.
Top with your beef and salsa mixture.
Then cook on high for 3-4 hours or on low all day.
Top with cheese for the last few minutes and let it melt in. Serve with corn, rice, and a side salad.
Notes
I bought everything except the cheese at Aldi. We buy our cheese at Costco, because it's cheaper in the 10 lb bags.
