Step 1: Prepare the Zucchini

1. Grate the zucchinis using a box grater.
2. Place the grated zucchini in a clean kitchen towel or cheesecloth and squeeze out as much water as possible. Removing excess moisture is essential for crispy bites.
3. Set the zucchini aside.

Step 2: Mix the Ingredients

1. In a large mixing bowl, combine the grated zucchini, chopped spinach, crumbled feta, garlic, breadcrumbs, egg, oregano, salt, and pepper.
2. Mix well until all ingredients are evenly incorporated. The mixture should hold together when squeezed. If it feels too wet, add more breadcrumbs.

Step 3: Shape the Bites

1. Scoop about 1-2 tablespoons of the mixture and shape it into small, round balls or patties.
2. Place the shaped bites on a plate or tray.

Step 4: Cook the Zucchini and Spinach Bites

Option 1: Baking

1. Preheat the oven to 375°F (190°C).
2. Line a baking sheet with parchment paper and lightly brush with olive oil.
3. Arrange the bites on the baking sheet and brush the tops with a little olive oil.
4. Bake for 20-25 minutes, flipping halfway through, until golden brown and crisp.

Option 2: Frying

1. Heat 2 tablespoons of olive oil in a skillet over medium heat.
2. Add the bites in batches, being careful not to overcrowd the pan.
3. Cook for 3-4 minutes on each side until golden and crispy.
4. Transfer to a paper towel-lined plate to drain excess oil.

Option 3: Air-Frying

1. Preheat the air fryer to 375°F (190°C).
2. Arrange the bites in a single layer and lightly spray with olive oil.
3. Air-fry for 12-15 minutes, shaking the basket halfway through, until crisp and golden.
