Potluck

buy pre-shredded cheese when possible. you also get little mozzarella pearls in the specialty cheese section so you don't waste time trying to cut up little pieces yourself

bagged lettuce is the way to go! don't worry cutting the lettuce yourself - nobody will know it was a bagged mix

you get olives that are already pre-. just drain

buy pre-washed and cut broccoli and cauliflower and save yourself a of washing and cutting
