In a couple weeks, I will be hosting a HS graduation party for my twins. Probably 50-75 people in and out, maybe 1/2 teenagers. My dad ( a butcher) will be cooking beef tenderoin and marinated chicken breast and making sandwiches out of both (on nice Iggy's rolls) He has asked that I have an assortment of spreads for the sandwiches. The beef will be grilled simply with salt and pepper rubdown, the chix will be marinated in lemon, rosemary and garlic. I have a horseradish mayo but whatelse???
