Preheat oven to 350 degrees.
Place the first 6 ingredients (beef through garlic powder) in a large bowl.
Using your very clean hands, gently blend ingredients well; form mixture into 2-inch meatballs then place them 1/2 inch apart on a large baking sheet lined with parchment paper.
Bake for 20 to 25 minutes or until internal temperature reaches 160 degrees and meatballs are golden-brown.
In a food processor, place the next 4 ingredients (basil through pine nuts); pulse until almost smooth.
Gradually drizzle in olive oil and lemon juice; pulse until smooth.
Serve with meatballs.
