Grate the zucchinis using a box grater and place them in a clean kitchen towel.
Sprinkle with a pinch of sea salt and let sit for 10 minutes to draw out moisture.
Squeeze the towel forcefully over the sink to remove as much liquid as possible from the zucchini.
In a large bowl, whisk the eggs then stir in the squeezed zucchini, almond flour, sliced green onions, and black pepper.
In a separate small bowl, whisk together the Greek yogurt, chopped fresh dill, minced garlic, and lemon juice to make the sauce.
Heat the olive oil in a large non-stick skillet over medium heat.
Drop spoonfuls of the zucchini mixture into the pan, flattening slightly with a spatula.
Cook for 3-4 minutes per side until golden brown and cooked through.
Serve the warm fritters immediately with a generous dollop of the dill yogurt sauce.
