Wow, never heard of a walking taco before?! Sounds interesting...
At my graduation party (and a lot that I attended) we had large trays of different foods. Sausage/peppers/onions, penne voldka, ziti, meatballs, roastbeef, chicken franchaize, rolls, regular salad, and pasta salad. We had a big cake and one of big bowl of assorted berries, and another of assorted melon.
Maybe this is a regional thing?
I do really like the idea of tacos though, I love Mexican food!
I would definetly do some kind of dip and a lot of it!
I make layered dip occasionally that consists of:
refried beans on the bottom
then some ground beef
layer of sour cream
layer of salsa
layer of cheese
then heat it up
..add shredded lettuce, tomatoes and black olives to the top.
jalepenos optional
mmmm, could go for some right now!
Whatever you do, make a lot of food! Kids can EAT!
Then if there's extras, you always have leftoverss!
