I often have leftovers from the previous night's dinner, like stew or vegetables. It usually contains some beans, tofu, chicken or fish. Or an avocado, sprinkled with salt, or a bowl of homemade soup and a couple pieces of fruit. Afternoon snack consists of nuts (any and all kinds), a piece of fruit and a piece of dark chocolate. I keep a small knife and cutting board at work to slice up things like tomatoes and cucumbers.
