Grilled Chicken with Tomato-Avocado Salsa

Ingredients for the salsa:

4 ripe plum tomatoes, chopped or 12 cherry tomatoes, halved

1/2 small red onion, finely chopped

1 jalapeño chili pepper, seeded and diced

2 tablespoons chopped fresh cilantro

1/4 cup fresh lime juice

1/2 avocado

Ingredients for the chicken:

1/2 cup non-fat, plain yogurt

1/2 small red onion

1/4 cup fresh lime juice

1/4 cup fresh cilantro

4 boneless, skinless chicken breasts, about 4 to 6 ounces each

salt to taste

freshly ground black pepper

Directions for the salsa:

1. In a small bowl, combine the tomatoes, red onion, pepper and cilantro.

2. Chop the avocado and sprinkle it with 2 tablespoons of lime juice to keep it from browning. Add the avocado and remaining lime juice to the bowl and toss to combine. (This can be made in advance and stored in the refrigerator for up to 1 day.)

Directions for the chicken:

1. In a small food processor, puree the yogurt, red onion, lime juice and cilantro to make a yogurt marinade.

2. Transfer the marinade to a shallow bowl or a plastic bag. Add the chicken and coat well with the marinade. Refrigerate for 1 hour or up to 8 hours.

3. Preheat the grill to medium-high.

4. Remove the chicken from the marinade, discard the remaining marinade and season the chicken with salt and pepper. Grill the chicken on both sides until it is cooked through, about 6 minutes per side.

5. Serve the chicken with tomato-avocado salsa.
