Wash and cut off the brown ends of the Brussels sprouts and slice in half, lengthwise. Toss with salt, pepper, garlic; seasoned to taste and olive oil to coat. Place on baking sheet and roast in oven for 12-15 minutes at 400'.
Barefoot Contessa makes a similar recipe. She leaves hers whole and roasts for a longer period of time.
~My side note:
I don't measure my ingredients for this, I just eyeball it. Since I am the only one who eats these, I just grab a good handful or two of the sprouts. These are really great, my husband is just afraid to even try them! At least my girls will try them.
