Another 2 hour casserole my mom would make is:

Texas Hash

1 pound ground beef

2 sliced onions

2 chopped green peppers

2 cups canned tomatoes

1 cup water

1 cup uncooked rice

1 t. chili powder

1 t. salt

Saute' beef, onions and peppers until beef is browned.  Add rest of the ingredients and cook in an instant pot for 20 minutes.

Enjoy!    💜
