2 lbs raw boneless skinless chicken breasts
1/4 cup soy sauce
3 T bottled margarita mix
1 T tequila
1 T lime juice
1 t. dry mustard
1 t. minced garlic
Combine all ingredients in a large freezer bag. Mix well, seal, and freeze.
Serving Day: Slice each breast in half horizontally, so that no piece is more than 1" thick. Arrange chicken slices on a greased broiler pan. Broil chicken 5" from the broiler, turning frequently and basting, for 15 to 20 minutes, or until a thermometer inserted into the thickest part of the chicken reads 170°. Do not baste during the last 5 minutes of cooking. If you prefer, chicken can be grilled over medium heat for approximately 30 minutes, turning and basting every 5 minutes. Do not baste during the last 5 minutes of grilling. Discard remaining marinade.
