I'm considering doing my own catering. Well, my mom is trying to talk me into not hiring a caterer and just having my family cook the food instead and serve it buffet-style and my guests will serve themselves. She's wanting to do things like cocktail wienies, meatballs, chicken salad, and maybe a big pot of gumbo or jambalaya or something. I'm having about 75 guests and am freaking out that there won't be enough food. She told me today, "when was the last time you went home from a wedding full?" Well, I don't want to send my guests home hungry! So, if I do decide to do this my mom's way (she's paying for the wedding, so I may not have a choice), what can I serve that will be cheap, good, filling, and still look elegant and sophisticated and not like I just threw some stuff in the microwave and served it?
