Well, okay, so we had this last night, but you know what I mean! This is is such a simple marinade for chicken I found on the internet the other day. (please forgive, but I can't for the life of me remember exactly where!)
4 chicken breasts
1/2 c buttermilk
2 T fresh chopped dill
2 T lemon juice
1 T zest
3 cloves garlic minced
Marinate for at least 30 minutes or overnight and then grill. Delicious!
