Preheat oven to 400 degrees F. Line a large, rimmed baking sheet with foil and spray with nonstick spray. Set aside. In a large bowl, combine all the meatball ingredients well. Divide the meatball mixture evenly into 25 meatballs. Place them on half of the prepared sheet pan in a single layer.
On the other half of the sheet pan, spread out the broccoli. Drizzle with the olive oil and sprinkle with salt and pepper. Toss with your hands. Bake for 25 minutes.
Meanwhile, prepare rice according to package directions.
Combine sauce ingredients in a large bowl. Set aside. Once meatballs have cooked for 25 minutes, drizzle the sauce over the meatballs and toss them evenly. Return to the oven and cook another 5 minutes.
Divide rice evenly among 5 meal prep containers. Place 5 meatballs in each container. Evenly divide broccoli.
