Best Chicken Pasta Salad Recipe

2 boneless, skinless chicken breast halves
3/4 cup steak sauce
1 (12 ounce) package fusilli pasta
2 cubes chicken bouillon
1 Vidalia onion, diced
2 avocados - peeled, pitted and diced
1 cup halved cherry tomatoes
1 cup Ranch-style salad dressing

1 Preheat an outdoor grill for high heat. Place breasts into a glass baking dish and marinate in steak sauce for 15 to 60 minutes.
2 Grill chicken until no longer pink and the juices run clear. Remove from grill, and chop into bite-size pieces.
3 To a large pot of boiling water, add bouillon cubes and pasta. Cook pasta until al dente. Drain, and rinse under cold water.
4 In a large bowl, combine chicken, pasta, onion, avocados and tomatoes. Mix in salad dressing, cover, and refrigerate until chilled.
