OK, OK, this one isn't the healthiest recipe in the world. But it's really good and really easy -- a new twist to the basic grilled cheese.
Whole Grain Bread (Not just whole wheat - make sure it's got real grains in it!)
1 lg. Onion
1 Lg. tomato
Cut onion in slices and sautee until soft. Butter one side of both slices of bread. Place one slice of bread (butter side down) in a pan over medium heat and layer with ingredients in this order: One cheese, cooked onion, another cheese, cilantro pieces and tomato slice, final cheese, then finish with the last piece of bread, butter side up. Flip and cook to until golden.
