Substitute grits for bran in banana bran muffins?
I asked my mom for the banana muffin recipe she used to make when we were little, and discovered it's a banana bran muffin recipe! I had no idea, and I don't have bran. I do have Gold Medal whole wheat flour, Quaker quick 5-min grits, and Indian Head yellow corn meal. What would make the best substitute for bran?
