In a blender, combine the boiled spinach with the drained and rinsed chickpeas. Season with salt, olive oil, and lemon juice, and blend until creamy.
Meanwhile, heat the protein piadina in a non-stick skillet.
Assemble the piadina: spread a generous layer of spinach hummus on the base, and top with crumbled feta cheese, halved cherry tomatoes, and fresh spinach leaves.
Finish the piadina with a drizzle of raw olive oil.
