Caramelize the onions: Heat 1 tbsp olive oil in a skillet over medium-low heat. Add diced onion and brown sugar; cook 10–15 minutes, stirring often, until golden and soft. Let cool slightly.
Prepare the aioli: In a small bowl, mix mayonnaise, Greek yogurt, apple cider vinegar, garlic powder, and caramelized onions. Season with salt and pepper to taste and refrigerate.
Cook the beef: Heat remaining 1 tbsp olive oil in a large skillet over medium-high heat. Add ground beef, season with salt and pepper, and cook 6–8 minutes until browned and cooked through. Drain excess fat if needed.
Assemble the bowls: Layer romaine lettuce in bowls, then top with beef, roasted potatoes or fries, and sliced tomatoes. Drizzle or dollop with caramelized onion aioli.
Serve: Garnish with extra onions or herbs if desired. Serve warm.

Cook onions low and slow for best caramelization.

Use ground turkey or plant-based meat for a lighter version.

Make the aioli a day ahead for deeper flavor.

Swap fries for sweet potatoes or cauliflower bites for variation.

Serve in lettuce wraps for a low-carb option.
