I've been covering for a co-worker for a month now, and am exhausted. I haven't the energy to go to the store and get additional ingredients, but I bought a few large organic heirloom tomatoes, some sweetcorn and green onions, and mozzarella at farmer's market yesterday and have some fresh basil from the garden. I also have a can of crab meat I need to use soon, but I don't have eggs for crabcakes. I also have lemons on hand, but that's about it for my fridge. What can I make with these ingredients that doesn't require a lot of effort?
