Preheat the oven to 400F.
In a skillet over medium-high heat, melt the butter. Cook the onion, shallot, garlic, celery, red pepper and parsley until softened, about 4-5 minutes.
Reserve some of the cooked veggies for the bottom of the baking dish. Deglaze the pan with white wine and let cook for another minute. Add the bread, salt, freshly ground black pepper and thyme. Mix to combine thoroughly. Gently fold in the crab meat.
Rinse and pat dry the sole fillets. Squeeze some fresh lemon juice on the filets. Spread the stuffing along the filet and roll it up.
Place reserved cooked veggies in the bottom of a buttered baking dish. Place the rolled up sole filets, seam side down, on top of the veggies.
Cook covered with foil for 15 minutes. Take the foil off and continue to cook for another 5 minutes uncovered. Serve with Rice Pilaf and Orange and Red Onion Salad.
