Chicken Pasta Salad

2 boneless chicken breasts

3/4 cup steak sauce

1 (12 ounce) package fussili or bowtie pasta

2 chicken bouillon cubes

1 medium Vidalia onion, diced

2 avocados, peeled and diced

1 cup halved cherry tomatoes

1 cup blue cheese or ranch salad dressing

Marinate chicken breasts in steak sauce for 15 to 60 minutes. Grill until done and chop into bite−size pieces. In a large pot of boiling water, add the bouillon cubes and cook pasta until al dente. Drain and rinse under cold water. In a large bowl, combine chicken, pasta, onion, avocados and tomatoes. Add salad dressing, mix and refrigerate until chilled. Stir in additional salad dressing when ready to serve, if desired.
