Place all ingredients except bread and butter (tofu, milk, flour, nutritional yeast, maple syrup, vanilla, black salt, cinnamon and nutmeg) into blender. Blend on high to break down tofu and incorporate all ingredients. (You don't want little bits of tofu so blend well). Then pour batter into pie plate or similar container to be able to coat bread slices.
Place first bread slice into batter and coat on both sides. If more than one slice of bread fits without overlapping, add those now too.
Heat non-stick skillet on medium to med/high heat. Add butter (or coconut oil).
When butter is melted and pan is hot, add soaked bread slices to pan to fit, without overlapping. Don't crowd pan. (I like to sprinkle just a pinch more black salt and cinnamon on top of bread, after adding to pan.) Now add more bread to batter in pie plate to soak on both sides while first slices are cooking.
Dont be in a rush to flip bread slices in frying pan. Let them cook for approximately 5-7 minutes to form a golden crust. Then carefully slide spatula (very thin type spatula works best), under slices, check for golden/ light brown color and then when the spatula easily glides under bread, flip to cook on other side.
Continue until all batter is used. You may need/like to add more butter/coconut oil to pan with each new addition of bread slices to achieve the best rich, golden fried outcome. Depending on thickness and size of bread and length of time soaking, you should get about 8-10 slices, more or less. Leftovers freeze well, too!
I like to top with frozen berries that have been cooked down in the microwave or on the stovetop mixed with a bit of maple syrup.
