Sour the cleaned fish with the lemon juice, pepper and salt.
Roughly dice the tomatoes, cut the spring onions into rings and chop the garlic. Crumble the sheep`s cheese and mix with the diced tomatoes, spring onions, garlic and olives.
Grease a baking dish with olive oil and place the fish fillet in it. Put the sheep`s cheese and vegetable mixture on top. Remove the thyme leaves from the branch and sprinkle over them.
Bake the whole thing in a preheated oven for 30-35 minutes at 200 ° C.
Serve with fresh baguette and a crunchy salad. Maybe a dry white wine and the summer evening is almost perfect.
