In a small bowl wisk together dipping sauce ingredients. Set aside.

In a large bowl wisk together flour, baking powder, and salt. Add milk, oil, and eggs. Wisk until just combined, leaving batter slightly lumpy. Do not over-mix.

Set waffle iron to regular setting. Let batter rest while waffle iron heats up.

When heated, spray iron with cooking spray. Pour 1/3 cup batter in each side. Close and cook waffles to pale yellow, just barely finished.

Open iron, do not remove waffles. Top one waffle with one slice of swiss, then ham and turkey (slices folded in half), then a slice of gouda.

Move second waffle on top of fillings. Close waffle iron, pressing top down gently to squeeze sandwich together. Cook to golden brown.

Plate. Dust with powdered sugar and top with sliced berries if desired. Serve each with 1/4 cup dipping sauce. Enjoy!
