Roasted pepper and tomates filled with vitamins and minerals. Combine peppers, tomatoes, onions, garlic, parsley in a bowl with your fingertips. Squeeze the juice of the lemon with the lemon half sitting upright. This will help prevent the seeds from falling into the bowl. The lemon juice will spill down over the sides of the lemon and the seeds will remain with the fruit. Use red, green, yellow or orange bell peppers to make this delicious side dish even more colorful.
