This black bean soup is super yum and healthy!
I make my own chipotles in adobo using those long skinny green spicy peppers that you can find any where. If you can't find limes because it isn't the two months of the year that we can get limes here, then you can just use lemon or try a young green lemon, its not quite a lime, but more lime-like.
I find that this recipe needs more spices so just add more in as you like, overall this is an awesome and quick prep recipe.
You can also try sour cream instead of yogurt, add green onion and a few tortilla chips as a topping, or let people add their own fixings.
