Preheat your oven to 400°F and toss the cubed sweet potatoes with 1 tsp of extra virgin olive oil and a pinch of sea salt.
Spread the potatoes on a parchment-lined baking sheet and roast for 20-25 minutes until the edges are caramelized and tender.
While the potatoes roast, heat the remaining 1 tsp of olive oil in a large skillet over medium-high heat.
Add the 85/15 ground beef to the skillet, seasoning with garlic powder, sea salt, and black pepper, and cook until browned and cooked through.
In a separate small non-stick pan, fry the egg until the whites are set but the yolk remains golden and runny.
Prepare the burger sauce by whisking the Greek yogurt and yellow mustard together in a small bowl until smooth.
Assemble the bowl by placing the chopped romaine at the base, followed by the roasted sweet potatoes and the cooked ground beef.
Top the bowl with the fried egg, sliced avocado, red onion, cherry tomatoes, and chopped pickles.
Drizzle the creamy yogurt sauce over the entire bowl and serve immediately while the beef and potatoes are hot.
