Creating delicious veggie pancakes is an easy process if you follow these simple steps:

1. Prepare the Vegetables: Grate the zucchini and carrots, and chop the spinach and onion. Place the grated zucchini in a clean cloth and squeeze out excess moisture.
2. Mix Dry Ingredients: In a large mixing bowl, combine the flour, baking powder, salt, and black pepper. Whisk together until well blended.
3. Mix Wet Ingredients: In another bowl, whisk together the eggs and milk until fully combined.
4. Combine Mixtures: Pour the wet mixture into the dry ingredients and stir until just combined. Add the grated zucchini, carrots, spinach, and onion. If using, fold in the shredded cheese.
5. Heat the Pan: In a non-stick skillet, heat 1 tablespoon of olive oil over medium heat.
6. Cook the Pancakes: Pour about 1/4 cup of batter onto the skillet for each pancake. Cook for about 3-4 minutes until bubbles form on the surface and the edges look set.
7. Flip: Carefully flip the pancakes and cook for another 2-3 minutes until golden brown.
8. Repeat: Continue this process with the remaining batter, adding more oil as needed.
9. Serve Warm: Once cooked, transfer the pancakes to a plate and keep warm while you finish cooking the rest.
