A great, and easy, thing I like to do with left over meats (like steak, pork, chicken, etc...) from previous night's dinners, is turn them into a potato hash and have them for breakfast. I had a left over pork kebab from a
dinner earlier in the week, so I took all the pork and veggies off the skewer, and cubed them (below).

Use the same amount of potatoes (any kind) as leftovers, and cube them the same size too. Blanch the potatoes lightly (boiling water for about 5 minutes works for me), and drain. In a non-stick pan large enough to hold everything, add a tablespoon or two of oil (spray if you prefer), and get the pan hot.
Saute the potatoes first, alone, for 10-15 minutes or until light golden brown. Add in your leftovers. At this point, you can also add any desired items that weren't included in the leftovers, like onions, mushrooms, peppers, and spices. Cook for another 5-10 minutes.
In a separate pan or pot, prepare and egg or two, your favorite way. I like sunny side up, or anything with a runny yolk. Serve eggs over the potato hash and garnish with basically anything really; Salt, Pepper, Parsley, Cilantro, Raw Onion, Scallion or Chives, etc ... and enjoy!
