I'm trying to create a huge spicy stew, something that has low fat, low carbs, tastes good, and has a ton of differing sources for vitamins. So far my list is:

Chicken breast (could trade for a lean beef if yall think it'd better)
garlic clove
2 onions
carrots
mushrooms
1 head of cabbage
a few tomatoes (least sure of this one)

All finely chopped and boiled in water for ~20 minutes. I haven't tried this yet, should be making in a few days though. I'm looking for more ideas in what to put in it, and if anyone has spotted something that won't go together in it. Also, how I might season it besides the obvious salt and pepper.

Thanks
