Bring a small saucepan of water to a boil. Season the water with salt, then cook the peas for about 2-3 minutes. Drain completely and set aside.
In a blender, blend the eggs, 1 teaspoon salt, creme fraiche, goat cheese, flour and oil until smooth. Transfer to a bowl and stir in the peas and chives.
Heat a little oil in a non-stick skillet over medium heat. Cook the pancakes in batches using a 1/3 cup to measure and pour the batter into the pan. Cook for about 2-3 minutes, then turn when the edges are bubbly and the bottom of the pancakes are golden. Flip and cook on the other side for about another minute or two. Continue until all the pancakes are cooked.
Drizzle with melted butter and served sprinkled with chives and topped with tzatziki.
