BROIL peppers for 15-20 minutes or until skins are blackened and blistered, turning occasionally. Place peppers in a tightly closed bag and let stand for 10-15 minutes. Remove skins and seeds. Cut into thin strips and set aside.
BRING a large pot of water to a boil.
HEAT olive oil in a large skillet over medium heat. Add garlic and saute until slightly yellow.
COOK pasta according to package directions.
Meanwhile, ADD cauliflower florets to the skillet and saute for 3-4 minutes (skip this step if cauliflower is omitted).
ADD roasted bell pepper strips to the skillet and saute for 2 minutes. Season with salt and pepper.
DRAIN pasta, reserving 1/3 cup of cooking liquid. Toss pasta with the sauce. If needed, add some cooking liquid to the skillet.
TOSS pasta with parsley and mix well. TOP with cheese before serving.
