If you are not already cooking your veggies this way, jump in!  Just about everything is better roasted.  Here are some little tricks to make it even better:

• Add a sprinkle of sea salt and fresh ground pepper
• Add a grated garlic clove or two (garlic powder works also) and 1/2 tsp tumeric, and a dash of salt.
• To add some heat, try a pinch of fresh hot red pepper flakes and a dash of salt.
