Preheat your oven to 400°F (200°C) and lightly grease a baking sheet.
Boil the medium potato until tender. Once cooled, peel (if desired) and mash in a bowl.
Lightly mash the green peas by hand or pulse briefly in a food processor, leaving some texture.
In a large bowl, combine the mashed potato, mashed green peas, chickpea flour, and egg whites. Season with salt, pepper, and any additional spices (such as cumin or paprika) to taste.
Mix well to form a cohesive patty mixture. If the mixture feels too loose, add a bit more chickpea flour until it can hold its shape.
Form the mixture into small, evenly sized patties and place them on the prepared baking sheet.
Bake in the preheated oven for 20-25 minutes, flipping halfway through to ensure even crisping, until the patties are golden and firm.
While the patties are baking, prepare the fresh cilantro chutney. In a blender or food processor, combine the chopped cilantro, lemon juice, green chili, garlic, olive oil, and a pinch of salt. Blend until smooth; add a splash of water if needed to adjust the consistency.
For serving, plate the crispy patties with a side of non-fat Greek yogurt (or drizzle it as a cooling dip) and a generous spoonful of fresh cilantro chutney.
Enjoy your flavorful, protein-balanced meal!
