Pre-heat a deep skillet or wide 4-quart saucepan over medium heat.
Add the EVOO, two turns of the pan, and the garlic, then grate the onion juice into the skillet. Cook for 2 minutes, then add the rice and barley. Season with salt and pepper and cook for 2-3 minutes more. Add the wine, raise the heat to medium-high and cook away the liquid, about 1 minute. Add a few ladles of the warm stock to cover the rice and barley, then drop in the ground meat in small bits. Stir frequently and continue to ladle in the stock until the rice and barley are cooked al dente, about 22 minutes. Stir in the cheese, adjust the seasoning and garnish with the parsley.
