1 3/4 cups flour
1 TB baking powder
spoonful sugar
pinch salt
4 beaten eggs
1/2 stick melted butter
1 1/2 cups milk
Mix all the dry ingredients together, then all the wet ingredients and then the two groups together. Add a couple handfuls on sliced green onion. If trying the ham and cheese combo, make sure the cheese is between slices of ham, so it doesn't melt into the batter and create strangeness. Also, the batter can be spread very thinly upon the iron and atop the ham- the super eggy recipe will fluff up to fill any holes or patches. Waffle iron should puff open a bit while cooking; don't worry about it and don't bother pressing it shut. It's all good.
Other mods: use 3 eggs and more butter for a crispier, more traditional waffle.
And using soy milk instead of regular milk definitely weighs down the recipe, creating slightly tougher, duller waffles. :(
