My IRL friend MotherofBlessings gave me this tip yesterday: to easily use a slice or two of bacon in a recipe, prepare ahead of time! Take a pound of bacon and a long strip of plastic wrap. Lay a piece of bacon down, wrap it a time or two, then lay another slice on top of it. Repeat until the entire package is individually wrapped. Now wrap that in foil and freeze. You can easily get just a few pieces when a recipe calls for it!
I always save my bacon grease. Collect the rendered fat in a glass jar and store it in your fridge. Bacon drippings add so much flavor to foods, especially country gravy and refried beans. Also, a teaspoon of drippings along with a tablespoon of crumbles makes green beans incredible!
