Here's a couple that I've already done:
Unsweetened applesauce for oil or butter
Works great in breads, muffins and cake mixes. If you're not sure about it, just try swapping half the oil (so a recipe using 1 cup of oil would use 1/2 cup oil and 1/2 cup applesauce).
Whole wheat flour for white flour
Good for any baked goods. Because whole wheat flour is more dense, use 7/8 cup of whole-wheat flour for every cup of white flour.
Evaporated skim milk for cream
Easy swap (1 cup cream for 1 cup evaporated milk), same consistency, half the fat!
Rolled oats for breadcrumbs
Rolled oats give you more whole grain in the recipe.
Two egg whites for one whole egg
Cut the cholesterol and double the protein!
Greek yogurt for mayo (in tuna/chicken salad)
When you add in seasoning, you can't taste the difference and you'll save calories and fat, plus add protein.
Do you have any healthy recipe swaps you use?
