Step 1: Prepare the Batter

1. In a mixing bowl, whisk together flour, salt, and baking powder.
2. Add the dashi broth (or water) and eggs, mixing until a smooth batter forms. It should be slightly thicker than pancake batter.

Step 2: Mix in the Vegetables and Fillings

1. Fold in the shredded cabbage and green onions, making sure they’re evenly coated in the batter.
2. If using shrimp, squid, or beef, mix them in at this stage.

Step 3: Cook the Okonomiyaki

1. Heat a non-stick skillet or griddle over medium heat and add a little oil.
2. Pour half of the batter into the pan, spreading it into a round, pancake shape about ½ inch thick.
3. Lay the turkey bacon or beef bacon slices on top.
4. Cook for 4-5 minutes on one side, then carefully flip using a large spatula. Cook for another 4-5 minutes until golden brown and crispy.

Step 4: Add Toppings

1. Transfer the cooked okonomiyaki to a plate.
2. Drizzle generously with okonomiyaki sauce and Japanese mayonnaise in a zig-zag pattern.
3. Sprinkle with bonito flakes, aonori, and pickled ginger for extra flavor.

Step 5: Serve and Enjoy!

Serve hot with extra sauce on the side. Enjoy your homemade Japanese street food!
