Leftover steak goes on a tortilla pizza, leftover meat or veggies turn into a soup, leftover chicken becomes chicken salad.
I generally freeze 1/2 a casserole and eat it for lunch the next week. Nice to have a day off from cooking but still have a warm yummy home cooked meal. You can also take a casserole and turn it into a pizza like this or this or this.
Here's a recent example of repurposing...
Shelly's Beef & Bean Taco Salad
1/2 pound Ground Beef
1/2 a Maui Onion, diced
3 cloves Garlic, minced
1 (15 oz.) can Pinquitos (or Baby Pinto) Beans, rinsed & drained
1 cup Cooked Corn Kernels
1/2 teaspoon Oregano
1/2 teaspoon Southwest Seasoning (I use Emeril's)
Shredded Cheese
Sliced Black Olives
Sour Cream or Fage Greek Yogurt (I made a Spicy Yogurt Dip)
Brown ground beef till no pink is seen. Drain any fats. Add onions and garlic. Saute till onions are soft. Add corn (I used corn from a leftover ear I had BBQ'd the night before), beans and seasonings. Cook till heated through. Serve a dollop of beef & bean mixture on top salad greens and top with cheese, olives and Spicy Yogurt Dip.
Shelly's Spicy Yogurt Dip
3 oz. Fage Greek Yogurt (I use 2%)
1 teaspoon Mayonnaise
a few splashes of Cholula Hot Sauce (or your favorite)
a dash of Southwest Seasoning
Kosher Salt to taste
Mix together. Great to top Taco Salads or use as a dip with veggies or soy crisps.
The leftover Beef & Bean mixture from the salad became Beef & Bean Bites (Crustless Quiches) the following day. Any leftovers can become a Bite...
Shelly's Beef & Bean Bites
About 2 cups Beef & Beef Mixture (leftovers from Shelly's Beef & Bean Taco Salad)
1/2 cup Colby Jack or Cheddar Cheese, shredded
5 Eggs, beaten
1/2 teaspoon Kosher Salt
Preheat oven to 350. Mix all ingredients together. Spoon into lightly greased (Pam works great) mini muffin tins.
