Ingredients:

1 large onion, cut into 1/2-inch dice
2 teaspoons olive oil
1 whole head garlic, unpeeled
1 red bell pepper, ribs and seeds removed, cut into 1/2-inch chunks
1 tablespoon tomato paste
4 (6 ounce) boneless, skinless chicken breast halves
2 teaspoons paprika
Coarse salt and ground pepper
3 tablespoons reduced-fat mayonnaise
2 teaspoons freshly squeezed lemon juice

Method:

In a 2-quart microwave-safe dish, toss onion with oil. Place garlic in the center. Cover; microwave on high 5 minutes. Stir bell pepper and tomato paste into onion.

Rub chicken with paprika and 1/2 teaspoon each salt and pepper; place on vegetables, with thickest part of breast facing edge of dish. Cover; cook on high until chicken is opaque throughout, about 10 minutes. Remove chicken.

Remove garlic; slice off top, and squeeze cloves into a small bowl. Add mayonnaise and lemon juice; mash with a spoon. Stir into vegetables; spoon onto plates, and serve chicken on top.
