Quick and easy, I've used this marinade for grilling chicken, salmon, ribs, "country style pork", portabellas, skewers of button mushrooms and peppers, or just skewers of button mushrooms. I've also used it for broiling salmon in the oven. It seems like no matter what you use it on, it comes out great! I've used this at least 2-3 times a month for the last 2 years, sometimes several times a week...
1/4 cup lemon juice (or orange juice, though I've never tried it)
1/2 cup of olive oil
1 envelope of "Good Seasons" Italian Salad Dressing mix
3 Tbsp. of Vodka (optional, and again, have never tried it)
It's not a "soak" marinade, just brush it on or dip your chicken in it and hit the grill...
