Preheat oven to 400°
In a small bowl, whisk together all the “sauce” ingredients. Set aside.
In a large bowl, mix together with your hands all the “meatball” ingredients. Form them into even meatballs and place them on a parchment paper lined baking sheet. Make sure they’re off to one side.
On the other side of the baking sheet, add the broccoli and mushrooms.
Pour the sauce over the meatballs and veggies.
Bake them in the oven for about 20 minutes.
Serve with meatballs and chopped scallions and enjoy!
