Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Line a baking sheet with parchment paper.

Peel the sweet potatoes, then cut them into cubes. Place on the baking sheet. Toss the sweet potato cubes with olive oil, salt, pepper, garlic powder, and onion powder until evenly coated. Spread the sweet potatoes in a single layer on a baking sheet. Bake for about 30 minutes, or until they are crispy around the edges, stirring halfway through for even cooking.

In a large skillet, cook the ground beef over medium heat until browned and mostly cooked. Drain any excess grease if desired. Stir in the spices. Cook for a minute then add in the water. Allow to cook about five minutes on a low flame. Remove from heat.

In a small bowl, combine the mayonnaise, lemon juice, and Sriracha (or hot sauce of choice). Mix well to combine. Add water in slowly while mixing until it’s thin enough to drizzle.

In each serving bowl, layer the crispy sweet potatoes, seasoned ground meat, chopped lettuce, diced tomatoes, and diced red onion. Drizzle the prepared sauce over the top.
