Set a heavy bottomed cast iron or nonstick skillet (that has a lid) on medium high heat and add the oil.
Once the oil is nice and shiny, add the chopped onions and bell peppers.
Stir for about a minute and then add the frozen edamame, corn, and black beans.
Add the dry quinoa, taco seasoning and garlic powder. Give everything a big mix.
Add the broth and increase the heat to high. Add salt and pepper and cover the skillet.
Once the stuff in the skillet starts boiling, lower the heat to low/simmer, cover and cook for 20-25 minutes until the quinoa is cooked.
Wait for 5 minutes and then fluff with a fork.
Serve warm as such in a bowl topped with desire toppings, or tucked in a tortilla to make a taco or a burrito or as a dip with chips.
