2 cups whole-wheat flour (or 1 cup whole-wheat and 1 cup all-purpose flour)
2 tsp baking powder
2 tsp dried oregano
1 tsp onion powder
½ tsp salt
2 large eggs
1½ cup milk
1/4 cup olive oil
½ lb diced ham
1 cup shredded low-fat mozzarella cheese, plus more for topping
1 green bell pepper, diced
8 canned pineapple rounds, ½ inch thick each
2 cups tomato sauce, warmed
In a large bowl, stir together flour, baking powder, oregano, onion powder, and salt. In a separate bowl, whisk together eggs, milk, and oil. Add wet ingredients to dry ingredients and mix gently until everything is moist. Fold in ham, mozzarella cheese, and green pepper.
Grease a waffle iron with cooking spray and heat. Ladle ½ cup batter for each waffle into waffle iron and cook until golden brown and set, about 5 minutes. (Keep waffles warm in a 200°F oven while you cook remaining batter.)
Place pineapple rounds on waffle iron, close lid, and heat until tender and slightly charred, about 5 minutes.
Serve each waffle topped with 1⁄4 cup warm tomato sauce, a pineapple ring, and additional cheese.
