I've been using the marinades I found over at Life as Mom for quick and easy bulk freezer meals. I actually quick thaw them in a large bowl of cold water an hour or so before I want Hubby to grill them.
I make a lot of them at one time. I will make two bags of two marinades, or two bags of three marinades, so I have a lot of bags with chicken happening all at one time.
I put them in a bowl to keep them contained, but I have found that if I put the chicken in first, rather than putting the marinade in first, the bag stands up better. Then it's easier to get my measuring implements inside the top of the bag without messy spills down the sides. I don't like that.
I break the rules and write in Sharpie on my bag after I'm done too.
