*Note: If you're planning to serve this right from the skillet family style, be sure to use an oven safe skillet for optional cheese melting/browning at the end! Cast iron works really well here.
Heat a large skillet over medium-high (7 out of 10) heat. Add 1 tsp olive oil and swirl around the skillet. Once the oil is hot, add garlic and onion. Saute until fragrant (about 1-2 minutes), then add bell peppers and saute for 2-3 more minutes until slightly tender, but still crisp enough to hold their shape well. Remove pepper mixture onto a plate.
Add remaining 1 tsp of olive oil to the skillet. Once hot, add ground turkey and season with chile powder, cumin, and Oh My Spice! seasoning. Depending on how much sodium is in the salsa you'll be using, you may need to add salt here too. Break the ground turkey apart with a wooden spoon or spatula as it cooks.
While the turkey cooks, pre-heat oven to 450° (or broil).
When the turkey is mostly cooked through but still has some spots of pink, add salsa and stir to coat the turkey evenly. Return pepper mixture to the skillet, then add black beans and corn. Stir until well incorporated.
Optional: Once the turkey is cooked through, it's time to top with cheese and bake/broil to melt the cheese and get it golden. You could certainly do this in the microwave or stovetop, but I liked the golden edges I got in the oven. If using oven safe meal prep containers, divide the turkey mixture into 4 containers and top with cheese before placing in oven (double check the max temperature rating on your containers!). If you are serving family style, just add the cheese right on top of the turkey mixture in the skillet. Bake/broil for 4-6 minutes or until cheese is melted and you begin to see golden brown edges.
Top with any other desired toppings such as chives, cilantro, or sour cream/plain Greek yogurt before serving.
