For the desserts I would think about doing the tuxedo Brownie Cups pg26 Celebrate cook book or the Berries 'N Cream Wonton Cups pg 114 It's Good For You. The brownie and the cups can be made ahead of time and then just filled - you can even have guests come up and help if you want and you'll have at least 24 of each since you are using the mini muffin pan. For appetizer I think the Southwestern Snack Squares pg 31 Celebrate are good because you can make small servings and predo the crust and then put toppings on. Hope this was helpful. Good luck.
