Preheat the oven to 400°F. Heat 1 tablespoon of the oil in a nonstick ovenproof skillet over medium-high. Gently fry the onions until soft, add the tomatoes; cover and cook, stirring occasionally, until the tomatoes burst.
Whisk together the eggs, 1 teaspoon of the salt, and ½ teaspoon of the pepper. Pour over the vegetables in the pan and cook, stirring gently, until the eggs just begin to set, about 1 minute. Stir in the spinach and sprinkle with the goat cheese and transfer the pan to the oven. Bake until the centre is set, 10 to 12 minutes.
Serve with salad of choice.
