In a small mixing bowl, stir together the coconut sugar, ketchup, apple cider vinegar, coconut amino, and pineapple juice until it forms a thin syrup.Set aside.
Make the meatballs
Preheat the oven to 425℉. Spray a 9 x 13 baking dish with avocado oil to prevent sticking.In a large bowl, combine the ground beef, almond flour, egg, broth, garlic powder, onion powder, sea salt, and pepper. Mix well with a dough whisk or wooden spoon.
Using a small ice cream scooper, scoop out as many meatballs as you can (12-16), depending on the size of your scoop. Place the meatballs in the baking dish. Sprinkle the bell pepper chunks around the meat balls.
Pour the sauce evenly over the meatballs and bell peppers.Place in the oven and bake them for 20 minutes. After 20 minutes, add the broccoli florets and toss everything together to coat the broccoli in the sauce.Sprinkle the broccoli with an extra pinch of sea salt.
Bake for another 10 minutes or until the meatballs are fully cooked and the broccoli is tender.
Cool for 5 minutes before serving, this allows the sauce to thicken. Serve alone, over brown rice, or rice noodles.
