01 - Preheat oven to 425°F (218°C). Arrange frozen waffle-cut potato fries in a single layer on a baking sheet. Bake for 20-25 minutes or until golden and crisp.
02 - Meanwhile, in a skillet over medium-high heat, brown ground beef until fully cooked, about 6 to 8 minutes. Season with salt and pepper. For a vegetarian option, warm black beans in a saucepan for 3 to 5 minutes until heated through.
03 - Transfer hot waffle fries to a large oven-safe platter. Evenly distribute cooked beef or beans over fries. Sprinkle shredded cheddar cheese on top.
04 - Return platter to oven and broil on high for 2 to 3 minutes, until cheese is fully melted.
05 - Garnish with diced tomato and red bell pepper. Serve immediately while hot.
