In two weeks I'm hosting a small get together for a friend's birthday and I'm thinking about making paella for everyone. I'll be hosting about 15 people and want to make a large, traditional paella (I'm thinking about using chicken, chorizo, and shrimp for this one along with onions, peppers, and a few other veggies) and a smaller vegetarian paella (not sure about this one, but will probably use tofu, onions, peppers, roasted corn and maybe sundried tomatoes). I've never made paella before and I've been reading about it online - it doesn't sound too hard. Any suggestions from people who have made it? Any ingredients I should throw in beyond what I've already mentioned? I feel like the most difficulty will come trying to find a skillet big enough to hold the big paella - hopefully I won't spend a fortune trying to find one. Any advice appreciated!
