I couldn't find the angel food cake at the supermarket, so I ended up calling Dani and Monica to ask them to get it for me--they had trouble finding it at a different supermarket.
Once again, I keenly felt the lack of a table outside with the grill. Maybe I'll get one this week.
The Onion-topped Beer Burgers were pretty good, though I didn't get much taste of the beer. One amusing note: since we were doubling the recipe, we needed a second packet of french onion soup mix--but I wasn't paying attention, and handed Monica a packet of chicken noodle soup mix instead. It didn't obviously hurt the burgers.
The Grilled Three-Potato Salad was very nice; it had a nice tangy dressing, with a nice roasted-potato taste. I'd gladly make it again. Getting a grill basket to use instead of the folded-over sheet of aluminum foil might be a good plan, though.
As we were finishing dinner, a hard rain came up, and we gathered everything indoors. So we didn't make the Grilled Angel Food Cake.
We talked for quite a while about the origins of fantasy fiction styles, and then we played a game of the Car Wars Card Game, and then a late-running game of Settlers of Catan, in which Dani got a narrow victory.
