Shred the zucchini using a box grater and place it in a clean kitchen towel; squeeze firmly to remove as much moisture as possible.
In a large mixing bowl, combine the squeezed zucchini, ground turkey, eggs, almond flour, sliced green onions, garlic powder, sea salt, and black pepper.
Mix the ingredients thoroughly until the turkey is well incorporated and a thick batter forms.
Heat the olive oil in a large non-stick skillet over medium heat.
Scoop the batter into the skillet to form 4 to 5 equal-sized patties, flattening them slightly with a spatula.
Cook the fritters for 5-6 minutes per side until they are golden brown and the turkey is fully cooked through.
While the fritters cook, whisk together the Greek yogurt, lemon juice, and Dijon mustard in a small bowl to create the aioli.
Serve the warm fritters immediately with a generous dollop of the zesty aioli on top.
