Pour chicken broth in a pot on high and let boil. Add onions and peppers and carrots. Let boil for about 10 minutes or until carrots are tender. Add ramen noodles and stir occasionally. Add seasonings and stir. Taste and adjust to your liking. Everything should blend together. You should taste the soy sauce/oyster sauce but they should not overpower. If you really like heat add more sriracha sauce! I allowed it to cook for about 15 minutes on medium to reduce the broth and let the flavors come together. When everything has been added and the noodles are done, then add the spinach and let cook until spinach is just wilted. It's done!
