I decided to take a safer route instead of doing something crazy. Mario and I put hot dogs and hamburgers on the grill, I made my potato salad, and we had a huge selection of other appetizers like a veggie platter, chicken enchilada roll-ups from Annie's Eats (although I used plain tortillas), and a whole slew of chips and dips. I ordered a cake from Costco since I didn't feel like making one, but I did spend a whole bunch of time making these sugar cookies for her. Overall, the party was a huge success and I'm looking forward to my next opportunity to cater for someone!
Directions and recipes for these sugar cookies can be found at Annie's Eats.
