To prepare the oyster flour, mix together the flour, cornmeal, thyme, oregano, garlic powder, onion powder, salt, and pepper in a bowl.

Transfer the oyster flour to a large plate, and dredge the oysters in the flour.

Heat the oil in one very large saute pan or two medium saute pans over high heat until lightly smoking. Add the oysters and cook just until they are browned, 3 to 4 minutes per side, depending on the size. Drain well on paper towels.

Split each French roll in half and place 5 oysters on each roll. Drizzle with cayenne aioli and top with lettuce. Serve warm.
