Preheat the oven to 400°F and grease or line a baking sheet with parchment paper. Place the diced sweet potato on the baking sheet and then use your hands to coat them with 2 tablespoons of the oil. Sprinkle them with sea salt and bake in the oven for 15 minutes.Next remove the baking sheet from the oven and set aside. Place the drained diced peppers, beans, and corn on top of the sweet potatoes then add the remaining tablespoon of oil. Sprinkle the seasonings on top then use a spoon to stir everything together.Bake in the oven for another 15-20 minutes, until the potatoes and the peppers are light brown on the edges.Allow to cool for 5 minutes then transfer to a bowl with desired toppings and enjoy! Side note: I prefer to layer everything on a bed of baby spinach and top with shredded cheese, salsa, fresh lime juice, avocado and/ or cilantro.
