Using leftovers creatively

Last night for dinner we had tempeh spring rolls with peanut sauce. I sent the extras with Dan for his lunch at the farm, but I still had some tempeh that was leftover. For lunch, I minced garlic and ginger, and sauteed these in toasted sesame oil with onion, carrots, and lacinato kale. I topped this with the leftover peanut sauce and served it with a side of brown rice. So delicious!! How do other people use their leftovers creatively?
