Preheat oven to 350 degrees. Coat a regular (12-cup) muffin pan with cooking spray. Set aside.
To make bread crumbs: Toast 1 slice multigrain bread or whole wheat bread. Place in blender and pulse until made into crumbs.
In a large bowl, add the breadcrumbs and all meatloaf muffin ingredients. Mix together well.
Use a ⅓ cup measuring cup and scoop the meatloaf mixture into each muffin cup. Make sure the meatloaf mixture goes to the top of each muffin cup. Flatten the tops.
Bake for 40 minutes. Drain any fat by carefully tipping the pan over the sink. Run a knife around each muffin to loosen them from the pan.
Make the topping: Mix together ⅓ cup ranch dressing and 2 tablespoons Frank’s red hot original sauce. Before serving muffins, spoon about ½ tablespoon sauce over each muffin.
