1. Preheat the Oven: 

Preheat the oven to 400°F (200°C). Line two baking sheets with parchment paper or lightly grease them. 

2. Prepare the Meatballs: 

In a bowl, combine the ground American lamb, feta, almonds, breadcrumbs, almonds, egg, garlic, cumin, cinnamon, salt, and pepper. Mix gently until just combined (don’t overwork the meat). Form the mixture into 12-16 meatballs, about 1 inch in diameter, and place them on one of the prepared baking sheets. 

3. Prepare the Sweet Potato Fries: 

On the second baking sheet, toss the sweet potato fries with olive oil, smoked paprika, salt, and pepper. Spread them out in a single layer for even cooking. 

4. Bake the Meatballs and Fries: 

Place both baking sheets in the oven. Bake for 20-25 minutes, flipping the fries and rotating the trays halfway through. Ensure the meatballs reach an internal temperature of 160°F before serving. 

5. Prepare the Lemon Hummus Sauce: 

While the meatballs and fries bake, whisk together the hummus, lemon juice, lemon zest, olive oil, garlic, salt, and pepper in a small bowl until smooth. Adjust seasoning to taste. 

6. Assemble the Bowls: 

In each bowl, add a handful of arugula. Place a portion of sweet potato fries on one side and the baked lamb meatballs on the other. Drizzle with the lemon hummus sauce. 

7. Serve: 

Serve immediately, garnished with extra feta, pickled red onions, and fresh dill if desired.
