In a bowl combine the minced garlic, dried oregano ,and dried thyme. Add the extra virgin olive oil, fresh lemon juice, and whisk until all Ingredients are well combined. This will be the marinade for the fish fillets.
Arrange the fish fillets in a shallow dish and generously drizzle the prepared marinade over the fillets. Make sure each piece is fully coated on all sides.
Cover the dish and place it in the fridge for at least 30 minutes to infuse the fish with the marinade.
Meanwhile preheat your oven to 375 degrees F.
In a separate bowl, toss together the diced bell peppers, red onions, cherry tomatoes, black olives and capers with a drizzle of olive oil. Season with a pinch of sea salt and black pepper then toss to coat the vegetables evenly.
Once the fish has marinated, remove the dish from the fridge. Arrange the prepared vegetables in another baking dish and top with the marinated fish fillets. Place a few lemon slices on top of each fillet for added flavor.
Transfer the baking dish to the preheated oven and bake for 15–20 minutes, or until the fish is cooked through and flakes easily with a fork.
Carefully remove the dish from the oven. Garnish the fish with fresh basil leaves and additional lemon slices, if desired.
Notes
Everyone's oven works differently, so make sure you check the dish at the 15 minute mark. Overcooking the fish will actually cause it to turn dry and chewy, which is not what you would want.
Make sure you pat the fish dry and soak up all the excess moisture using paper towels before you marinate it. You don't want it all to be a runny mess.
Love the citrusy flavors of lemon? Add in some fresh lemon zest in addition to the lemon juice!
For extra Mediterranean flavors, you can also top the dish with some crumbled feta cheese right before you serve.
