Combine the ground turkey, pesto and a pinch of salt in a large mixing bowl. Using your fingers, form 1-inch meatballs. Place the meatballs on one side of a sheet pan and the bell peppers and broccoli florets on the other. Drizzle with the olive oil and a good pinch of salt. Roast until vegetables are tender and meatballs start to turn golden, about 30 minutes, then turn the oven to broil. Drizzle 1 or 2 tablespoons water over the broccoli, then put the sheet pan under the broiler until toasted, about 5 minutes.
For the parents, serve garnished with fresh basil, a lemon wedge and freshly grated Parmesan.
Now for the kids! In the meantime, boil the spaghetti in a pot of salted water until al dente. Reserve about 1/2 cup pasta water and drain the rest.
Toss the pasta with the pasta water, a tiny drizzle of olive oil and a small helping of meatballs and veggies. Garnish with cheese and serve!
