Pre heat oven to 180 degrees C.
If your rice is not yet pre-cooked, cook your brown rice according to packet instructions. This recipe allows for 2 cups of cooked rice, so freeze any leftovers.
Grate the carrot and set aside. Drain and rinse half the tin of lentils and place them in a bowl. Roughly mash them with a fork. Add beef mince, grated carrot, salt and pepper to the same bowl and combine ingredients well using your hands.
Roll the mixture in to small to medium sized meatballs (should make approx. 15 balls) and place the balls in oven proof dish (or two dishes if required).
Cover the balls well with your jar of passata. Sprinkle over grated cheese.
Pop in to your oven and bake for 30mins or so - until balls are cooked through. Pop grill on last minute if you want to brown the cheese a little more - but keep your eye on the cheese as it can burn very quickly!
While the balls are in the oven, steam cook your beans and broccoli florets over a boiling pot for a few minutes or until just tender.
Once balls are cooked through, assemble your plates or bowls with a serve of rice (large serving spoon or approx. 1/3- 1/2 cup), meat balls (approx. 3-4 pp) and your greens.
Season with more salt & pepper if desired.
