**Make the Burger Bowl:**
- Heat a pan over medium-high heat. Add the ground beef and cook until browned, breaking it up as it cooks. Season with garlic powder, onion powder, paprika, and a bit of salt. Cook for 5-7 minutes, then set aside.
**Prepare the Sweet Potato Fries:**
- Preheat the oven to 425°F (220°C). Toss the sweet potato fries in olive oil, cornstarch, salt, and pepper. Spread them out on a baking sheet and bake for 30 minutes, flipping halfway through. Alternatively, air fry at 425°F for 15 minutes, shaking the basket halfway.
**Assemble the Burger Bowl:**
- Layer the bottom of a bowl with chopped romaine lettuce. Place the cooked ground beef in the center, and surround with cherry tomatoes, pickles, onions, and shredded cheese. Add the sweet potato fries around the edge.
**Make the Special Sauce:**
- In a bowl, combine the mayonnaise, ketchup, pickle relish, mustard, vinegar, onion powder, salt, pepper, and cayenne pepper (optional). Mix well.
**Finish the Bowl:**
- Drizzle the special sauce over the burger bowl or serve it on the side. Add any optional toppings like avocado, crispy bacon, or a fried egg.
**Serve:**
- Enjoy your delicious, bun-less burger bowl, perfect for a quick, healthy dinner.
