Grease a 12-hole muffin pan (each cup approximately 3" in diameter) and set aside.
In a large bowl, combine eggs, coconut milk, and flour. Mix well until smooth.
Stir in tuna, corn, scallion, onion, black pepper, hot pepper sauce, and ¾ of the grated cheese. Mix thoroughly to combine.
Spoon the mixture into the prepared muffin pan, filling each cup 2/3 full. Top with the remaining cheese and tomato halves, then lightly sprinkle with paprika.
Bake in the preheated oven for 25 minutes, or until the tops are golden and the quiches are set.
Remove from oven and allow to cool on a rack for 10 minutes. Carefully remove quiches from the pan and serve warm.
