Preheat your oven to 375°F (190°C) and grease an 8x8-inch baking dish with olive oil to prevent sticking.
Heat a skillet over medium heat and add the olive oil. Sauté the diced onion until translucent, about 3 to 5 minutes.
Add the fresh spinach to the skillet and cook for 2 to 3 minutes, or until wilted. Remove from heat and set aside to cool slightly.
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until fully combined.
Add the shredded cheddar cheese, sautéed onion and spinach mixture, and halved cherry tomatoes into the egg mixture. Stir gently to combine.
Pour the mixture into the prepared baking dish and smooth the top with a spatula to ensure even cooking.
Bake in the preheated oven for 30 to 35 minutes, or until the quiche is set and slightly golden on top. A toothpick inserted into the center should come out clean.
Remove the baking dish from the oven and let it rest for 5 minutes before slicing into squares.
Serve warm or at room temperature. Enjoy your delicious crustless quiche squares!
