How about tea sandwiches. Egg salad, deli meets, ham salad, veggies, etc. My family did this at my baby shower and it went over really well. Super easy, just a couple loaves of bread (cut off the crust), your fixings and done. Fruit salad, green salad, pasta salad (noodles, pepperoni, black/green olives, cheese cubes, italian dressing), again super easy. Jello always goes over really well (rasp./strawberry jello, angle food cake-cubed, unthawed strawberry or raspberry and cool whip--mix in a big bowl--done). I hope this helps, all of these are super easy and dont take much time at all to make.
The recipe for the tortilla roll ups:
Soft taco shells about 6
2 packages cream cheese
taco seasoning
black olives--minced finely
soften chream cheese, mix in the taco season (to taste), add black olives (2-4 ounces). Mix well, spread on a taco shell, layer another taco shell and spread more of the mixutre (repeat until you have the thickness that you like--4-6 shells is enough). Cut into small bite size pieces. YOu can make three or four of these just alter the recipe for the amount you are making. YUMMY!
The ideas just keep coming:
Waterschestnuts wrapped in bacon
Depending on how many people you have for around 15 people I use three cans of water chestnuts (round/not sliced)
Soak the waterchestnuts in soy sauce over night (just enough to cover)
Wrap the water chestnuts in the bacon
either sprinkle or dip the waterchestnuts with brown sugar
Line baking sheets with aluminum foil (non-stick works best)
Bak in the oven at 375 until bacon is cooked and looks crip. I would suggest making lots of these, they go quick.
