Preheat the oven to 350º F.
In a large bowl, add mayonnaise, honey mustard, flour, eggs, milk and dry spice ingredients (salt, pepper and smoked paprika). Beat until ingredients are mixed.
Fold in already-cooked and flaked catfish, cheese, cooked bacon bits and sweet onion to large bowl mixture.
Spoon mixture into already-baked shells, about 1 large heap per shell.
Garnish each mixture in a shell with some green onion.
Bake on the middle rack of the oven for 20 to 24 minutes, or until a toothpick inserted in mini pie comes out clean. Cool on wire 5 minutes before serving.
