I make Kimchi Jigae, or Kimchi Soup, pretty often and the only staple I use is kimchi, obviously, and tofu. It's traditionally made with pork and other spices, but I like to experiment. For this I didn't have any meat ready that would be good but I found a package of crawfish tails I had been trying to figure out what to do with so I figured I'd try it out and see how it goes and it turned out so good.

Ingredients (none of these are exact, I tend to season by taste but I'll try to put an estimate of what I used

About 5 cups of water
2 cups of cabbage kimchi
A bottle of [Ajumma Republic Korean Kimchi Seasoning](https://www.amazon.com/Ajumma-Republic-Korean-Kimchi-Sauce/dp/B01M68C6A6)
1 lb of cooked, peeled crawfish tails
however much tofu you like.  I like a lot so I used 3 packages
2 TBSP onion powder (you can used minced onions as well)
2 TBSP garlic powder (likewise can use minced garlic or whole cloves if you like)
1 can tuna (I like the fishy taste it brings to the broth but it's optional)

Directions

Heat a big pot and put some oil in and fry the kimchi a bit.  I find it brings out the flavor and gives it a nice crunchy texture

Pour in the water and however much of the kimchi seasoning you like to taste

add tofu sliced into cubes, tuna, garlic powder, onion powder, and crawfish

bring to boil and let simmer 15-20 minutes

taste and if it's good, serve
