I also do the Italian dressing but never added Mayo. Will try that next go around. I have also marinated chicken breasts in margarita mix (just the mix, no tequila added).Recipe time:
chicken breasts, you choose the degree of skinless and boneless.
put in a gallon size ziplock bag, with a cup of zesty italian salad dressing and half cup of mayo of choice. Let marinate for an hour or two, longer is better. Grill it up and enjoy.
