Heat the 1 tsp of olive oil in your pan on medium heat. Sauté your scallions for 1 minute and sauté your spinach for 1 minute until just wilted. Transfer to a plate and set aside.
In a large bowl, add in the eggs, buttermilk and oil and whisk together. Next, sift in the flour, baking powder, baking soda, salt and pepper to taste, add in the grated parmesan and mix all until just combined - DO NOT OVERMIX. Lastly fold in the sautéd spinach mixture, crumbled feta and dill.
Heat a drizzle of olive oil in your pan on medium-high. Once hot, scoop about 1/3 cup of the batter onto the pan, gently flatten each out a little bit. Repeat and cook the cakes 3-4 minutes per side, lowering the heat to medium-low as needed to prevent burning. Serve with a scoop of sour cream and garnish with fresh dill.
