This is a quote from the washingtonpost.com - "Blueberries add cancer-fighting antioxidants to the patties and may slightly reduce the fat content of burgers. They also help make burgers that are made from drier, leaner ground beef, chicken or turkey into a juicier product." When making this burger you can use fresh blueberries. Omit the freeze-dried and wait until you finish with step #3. Then add the blueberries folding in gently, being careful not to mash or break. The burger really looks good when you use the fresh berries. You can also add 1/8 tsp. chili powder, 1/2 teaspoon hamburger seasoning, a pinch of cayenne 1/2 Tablespoon minced onion, 1/2 Tablespoon parsley. If you add these things add 1/8 of a cup of milk. Otherwise just use the simple recipe below.
