If cooking indoors, preheat oven to 400 degrees. Thoroughly rinse any fresh produce and pat dry. Prepare a baking sheet with foil and cooking spray. Toss potatoes, onions, corn, seasoning blend, 2 tsp. olive oil, and a pinch of salt on prepared baking sheet until combined. Spread into a single layer and roast in hot oven until onions are soft, 16-18 minutes.
While potatoes cook, pat steaks dry, and season both sides with ¼ tsp. salt and a pinch of pepper. Place a medium non-stick pan over medium heat and add 2 tsp. olive oil. Add steaks to hot pan, and cook until browned and steaks reach a minimum internal temperature of 145 degrees, 5-7 minutes per side.Top potato mixture with cheese. Coarsely crush crispy onions. Follow same plating instructions as grilling.
