I wish I had seen your post earlier! This may come a bit late, but in the future, if you have leftovers like this, I suggest making a homemade pot pie. They are really yummy, super cheap to make & feeds the whole fam.
Rather than using chicken (as in the original recipe) just cut up your pork into bite size pieces. You can use your green beans in the recipe too. If you need more veggies, just add a handful of anything you have in the freezer, or drain a can of whatever veggie you have on hand.
