Our landfills are full of still edible restaurant leftovers, not to mention pasta, sourdough starter and lots of other good food.  

Instead, try this:

• Beyond freezing take out leftovers, use tasty sauces to make another dish using a cooked protein.
• Some leftovers can be tossed in a blender with broth and turned into thick tasty soup.
• Rice can be fried with eggs to make breakfast.
• Pasta can be added to soups or mac and cheese. Wrap any leftovers in pie dough and make dinner hand pies.
• Mashers can become gnocchi and hash browns a frittata.
• When you finish the jar of pickles, use the juice to make salad dressing or in cocktails.
• The liquid in canned beans and vegetables can be added to soups.
• Pour cold coffee into ice cube trays and freeze to make blender shakes.
• Got too much sourdough starter. Add flour, salt and olive oil and seasonings, roll it out thin and bake briefly to make crackers.
