Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Spread the tomato sauce evenly over the gluten-free pizza crust, leaving a small border around the edge.
Sprinkle the garlic and herb seasoning over the sauce.
Using a spoon, create four small indentations in the sauce, evenly spaced apart.
Carefully crack an egg into each indentation, keeping the yolk intact.
Scatter the chopped spinach over the pizza, avoiding the egg whites.
Sprinkle the feta cheese evenly over the top.
Place the pizza on the prepared baking sheet and bake for 12-15 minutes, or until the egg whites are set and the crust is golden brown.
Let cool slightly before slicing and serving.
