Preheat the oven to 220 °C (425 °F) with convection grill.
Peel 7 garlic cloves and press them into the 5 tablespoons of olive oil using a garlic press.
Cut the 600 g sheep cheese into 1/2 cm thick slices using a sharp knife.
Place the cheese slices in a baking dish and drizzle with half of the garlic oil.
Wash and dry the 5 tomatoes, remove the stems, cut in half, and place on the cheese with cut side facing up.
Season the tomatoes with salt and black pepper, then drizzle with the remaining garlic oil.
Place the baking dish on the 2nd rack from the bottom and bake for about 15 minutes.
While the cheese is baking, wash the basil and cut it into fine strips.
Turn on the broiler, move the baking dish to the middle rack, and cook for 3-5 minutes until the cheese is lightly browned and the tomatoes are grilled.
Remove from the oven, sprinkle the basil over the grilled cheese and tomatoes, and serve.
