Every month we have a themed potluck at work- I pushed hard for tapas because I love it and I love to cook. Now we're doing it and I want to go all out and impress. I would be willing to do 2-3 dishes. The challenge is that everything has to be pre-made and preferably served cold, because all we have at work is a fridge, a toaster, and a microwave. Ideally I would make it the night before and bring straight to work in the morning. There is NEVER any good protein at these potlucks, so I would love to bring chorizo and/or shrimp. I'd like to do patatas bravas somehow or tortilla espanola. Help! Any ideas or guidance?
