Preheat your oven to 375°F (190°C).
Heat the olive oil in a small 6-inch oven-safe skillet over medium heat.
Add the ground chorizo to the skillet and cook for 5-6 minutes until browned and crispy, breaking the meat apart with a wooden spoon.
Toss in the fresh spinach and sauté for 1 minute until just wilted, then remove the skillet from heat and spread the mixture evenly across the bottom.
In a medium mixing bowl, whisk together the eggs, Greek yogurt, smoked paprika, sea salt, and black pepper until the mixture is completely smooth and creamy.
Carefully pour the egg and yogurt mixture over the chorizo and spinach in the skillet.
Place the skillet in the oven and bake for 12-15 minutes, or until the edges are golden and the center is set but still has a slight jiggle.
Remove from the oven, garnish with finely chopped fresh chives, and enjoy immediately.
