Ensure the snails are thoroughly cleaned and purged. Rinse them under cold running water.
In a large skillet, heat the olive oil over medium heat. Add the finely chopped onion and sauté until soft and translucent. Add the minced garlic and cook for another minute.
Stir in the chopped tomato, fresh parsley, fresh thyme, bay leaf, and paprika. Cook for about 5 minutes, until the tomato softens and the mixture becomes fragrant.
Add the snails to the skillet and stir to coat them with the tomato and spice mixture. Pour in the white wine and chicken broth. Bring to a boil, then reduce the heat and let it simmer for about 20-25 minutes, or until the snails are cooked through and tender.
If you prefer a thicker sauce, you can stir in the breadcrumbs at this stage. Cook for an additional 5 minutes to allow the sauce to thicken.
Remove the bay leaf before serving. Transfer the snails and sauce to a serving dish. Serve hot with lemon wedges on the side for squeezing over the snails.
Enjoy your meal!
