Preheat oven to 425F degrees, racks in the middle.
In a medium bowl, combine the flour, wheat bran, salt, baking soda and sugar.
Beat together the yogurt, egg, honey, and butter in a second larger bowl. Add the dry ingredients and fold in until everything comes together. Fold in any optional add-ins, raisins, nuts, and the like. Resist overmixing.
Either grease a mini-muffin tin with butter or line the tin with small muffin papers. Fill each 3/4 full. Bake 10 -15 minutes, until muffins are golden on top and cooked through. You can also make larger muffins in a standard size muffin pan with this batter, you just need to bake them about 5 minutes longer.
