Place the feta in the middle of a 2qt baking dish. Scatter whole garlic around and top with the cherry tomatoes. Drizzle with olive oil and sprinkle with red pepper flake, salt and pepper.
Bake in the oven for 20 minutes. Remove and stir the cherry tomatoes. Return to the oven for another 10 minutes.
Find and pull out the garlic cloves. Smash them with the back of the spoon against the side of the baking dish (they should be soft enough to easily fall apart). Stir in the garlic, breaking up the feta slightly and evenly distrubuting the cherry tomatoes.
Serve with pita chips or toasted bagette slices.
