This is a simple crock-pot soup that I made for Father's Day last year. We were meeting up for a winery tour in the morning, and then everyone came to my house for lunch, so I needed something that could take care of itself for a while. The times below are how our day went, but I'm sure it would be fine with cooking longer in part 1 and shorter in part 2.
2 c mixed dried bean
2 potatoes, cubed
2 quarts water
1 c uncooked macaroni
1 can Rotel tomatoes w/ green chilis
1 onion, chopped
2 cloves garlic, crushed
salt, pepper, basil, oregano
Part One: Rinse the beans. Put beans, potato pieces, and water in crock pot. Cook on High for 3 hours.
Part Two: Sauté the onion and garlic in oil until onions are soft. Add the onion and garlic, tomatoes, and macaroni noodles to the crock pot. Salt and spice to taste. (It needs more salt than I expected - canned beans have a lot of salt, while dry beans have none.) Cook on High for 1 hour.
