If you're making pasta salad or a shrimp Caesar, don't just make enough dressing for one meal. Double or triple the batch, and keep the remaining dressing in the fridge for another meal in the coming days--you could serve it with steamed broccoli on a baked potato. The same is true for pasta. Make twice as much as you need, and then save the leftovers in the fridge for pasta salads in the week ahead.
