roasted garlic The best way to spice up mashed potatoes or any veggie is to cut of the end of a garlic bulb and place it in foil. Pour olive oil over top and seal up in the foil. Place in the oven at 400 for about 15-20 minutes, or until bulb is soft. After it cools, squeeze the pulp into potatoes, over veggies, over meat - anything. By doing this, you don't risk eating any bits of the garlic.
