Chicken & Bean Soup with Corn Just Using What Is on Hand

I made this soup tonight with some ingredients I had in my pantry.

Here are the ingredients, more or less:

1/2 large onion, chopped and sauteed in a little oil
Then add the following to the pot and simmer for about 30 minutes:
1 can of chicken
3/4 cup frozen corn
1 can white beans
1 Tablespoon chili powder
1 teaspoon dried oregano
1 teaspoon of garlic powder
dash of hot pepper flakes
generous squirt of sriracha sauce
