Step 1

Preheat oven to 425°. Using your hands, mix ground turkey, egg, panko, cumin, onion powder, paprika, ¼ cup parsley, and ¾ tsp. salt in a large bowl. Working one at a time, scoop out small amounts of mixture and roll into 1½"-diameter balls (you should have 18–20 meatballs).

Step 2

Heat 2 Tbsp. oil in a large ovenproof skillet over medium. Wo rking in batches, cook meatballs until golden brown all over, about 2 minutes per side. Transfer skillet with meatballs to oven and bake until cooked through, 5–7 minutes.

Step 3

While the meatballs are baking, pulse almonds in a food processor until coarsely ground. Transfer to a medium bowl. Pulse fire-roasted peppers, garlic, vinegar, and cayenne in food processor until almost smooth. Transfer to bowl with almonds and stir in remaining ½ cup oil; season romesco sauce with salt.

Step 4

Spoon romesco sauce into shallow bowls and arrange meatballs on top. Finely grate lemon zest over and scatter coarsely chopped parsley on top.
