Prepare the Aromatic Base: In a large mixing bowl, combine the finely diced red onion, minced garlic, chopped sun-dried tomatoes, fresh dill, fresh mint, dried oregano, lemon zest, black pepper, and sea salt. Stir thoroughly to create a uniform, fragrant base.
Add Binder and Greens: Add the finely chopped spinach and the mashed chickpeas to the aromatic base. Mix until the spinach is well-distributed and the chickpeas are fully incorporated. This mixture will serve as the binding and moisturizing agent for the lean chicken.
Combine and Form Patties: Crumble the ground chicken breast into the bowl over the vegetable and chickpea mixture. Using your hands, gently fold and press the ingredients together until just combined. Be careful not to over-mix. Divide the mixture into 6 equal portions and form each into a patty about 3/4-inch thick.
Chill for Integrity: Place the formed patties on the parchment-lined baking sheet and chill in the refrigerator for at least 15-20 minutes. This crucial step helps the patties firm up and hold their shape during cooking.
Pan-Sear to Perfection: Place your skillet over medium heat and add the extra virgin olive oil. Once the oil shimmers, carefully place the chilled patties in the skillet, leaving space between them (cook in two batches if necessary). Sear for 5-6 minutes per side, until a deep golden-brown crust forms and the internal temperature reaches 165°F (74°C).
Rest and Serve: Transfer the cooked patties to a clean plate and let them rest for 3-5 minutes to allow the juices to redistribute. Serve warm on their own, in a whole-wheat pita, or in a crisp lettuce wrap.
