Prepare baking sheet by brushing with olive oil or lining with baking paper, then place the 2 feta cheese blocks on it.
In a bowl, combine minced garlic (1 to 2 cloves depending on size), red onion cut into thin strips, roughly chopped sun-dried tomatoes, and roughly chopped olives.
Add 10 dashes of olive oil to the mixture and stir well; use the oil from the sun-dried tomatoes container if available.
Season each feta block with pepper and sprinkle with dried oregano, rosemary, and thyme to taste.
Distribute the topping mixture generously over each feta block; the topping reduces during baking so load it generously.
Bake at 175°C (347°F) for 15–20 minutes until the cheese edges are lightly browned and bubbles form on the surface.
