I assume from your post that you are wiling to make meat. If so a super simple recipe is salsa chicken. Dump a jar of salsa into your slow cooker and add a couple of fresh ( not frozen) chicken breasts. Cook on high for about 2 hours. You can pull them apart (shredded and chunks, whatever) and make a taco bar... Empty the chicken and the salsa juices to a bowl and fill other bowls with shreaded cheese, sour cream, chopped scallions, rice and beans. Don't forget tortillas,too. That way the vegetarians can eat rice and bean tortillas. For the rice and beans, chop up 1 onion, 1 green pepper, 5 cloves of garlic and cilantro pretty small (alternatively, go to the Goya section of the supermarket, which is usually in the Mexican or the bean section, and get a jar of the green sofrito-- while you are there pick up some Adobo, too). Sauté in about 2 tablespoon of olive oil for a few mintues (don't let the garlic burn) add can of black beans, add some vegtable stock if you drain the beans-- about a 1/2 cup, and cook on low till warmed thru. Add some Goya Adobo seasoning, sqeeze in lime juice towards end (if you don't have lime, add vinegar-- about half a capful) If you want pink beans instead,throw in green olivesat any time, and also add tomato sauce (a small can, I use Goya for my beans) when you put the beans in, and don't use vinegar I'd lime-- the tomatoes provide enough acid. Have fun!
