Curried Lentils a la Crock Pot

1/2 sweet potato finely diced
1 onion
1 clove garlic

4 diced tomatoes
3 or 4 cups stock
1 bag lentils (we’re using pretty orange colored ones)
1 Table Spoon Curry Powder (unless you know how to curry things from scratch like Matt does)
salt, pepper
low for 3 or 4 hours, stirred occasionally because mine gets really hot and burns, even on low, if I’m not carefully
Sometimes I add lots of vegetables (green pepper, carrots, celery, anything) but not tonight because I don’t want to freak everyone out.
