Like most people, when I need a recipe or cooking advice, I head straight to the Physics Forums. OK, so I'm on the hook for an office pot luck contribution next week. I'm going to make some kind of hot appetizer. My first idea was frozen mini pastry puff appetizers (from Trader Joes) but it seems these are going to take 30 minutes in the oven. I'm looking for something in the 15 minute prep and cook time range. We have an oven on site, so that helps matters, but there may be a lot of competition for it as several people will be bringing things to heat up. Any brilliant ideas?
