Place quinoa and 4 cups of water in a medium saucepan. Cook according to package instructions. While quinoa is cooking, heat extra-virgin olive oil in a 12 inch cast iron skillet over medium-high heat.
Add bell peppers and onions to the skillet and cook stirring occasionally until the onions become translucent, about 7 minutes. Reduce heat to low and add in garlic, black beans, and tomatoes with chilies.
Cook for an additional two minutes, then remove from heat. Mix the salsa and cooked quinoa together until combined. Pour the quinoa into the vegetables in the skillet and stir until the mixtures are well combined.
Top with shredded cheese. Place cast iron skillet under the broiler until cheese is golden and bubbly, about 4 minutes. Be sure not to walk away from the dish while it's in the broiler otherwise something may burn.
