Step 1: Adjust oven rack to the middle position and heave oven to 400-degrees F.
Step 2: In a large bowl, whisk eggs, cheeses, oregano, and salt and pepper to taste.
Step 3: Heat oil and garlic in a large (12-inch) ovenproof nonstick skillet over medium-high heat until garlic starts to sizzle and turn golden. Add spinach and cook until excess moisture evaporates, about 1 minutes. Add the ham, shaking skillet to distribute evenly. Add egg mixture. Cook, without stirring, until eggs start to set around edges, about 1 minute.
Step 4: Transfer pan to the oven and bake until frittata is puffed and set, 10 - 12 minutes. Slide or invert onto a large plate, cut into wedges, and serve.
