Remember that song with the meatball that rolls out the door? You could think of this recipe as an ode to that runaway food. Except instead of spaghetti, you’ve got springy cavatappi—all the better for helping these turkey meatballs to bounce! The whole thing is still all covered with cheese, but you’ll also find herby basil pesto sauce and tender broccoli florets for a verdant burst of green.
