In a medium skillet, saute the onion and garlic in olive oil over medium heat. Remove the skillet from the heat and let cool briefly. In a small bowl, combine the bread crumbs and the capers, and then add the sauteed onion and garlic to the bowl. Stir the mixture together until thoroughly combined. If necessary, flatten the catfish fillets by placing them between 2 pieces of plastic wrap and gently pounding with a mallet or by rolling out with a rolling pin. Generously spread the bread crumb mixture on top of each fillet. Roll the fillets up, securing with a toothpick if desired. Heat a medium or large skillet over medium heat. Add enough olive oil to the pan for sauteing, about 1/4-inch up the side of the skillet, and let heat for 1 minute. Carefully place the rolled catfish fillets into the skillet, and cook until evenly browned on all sides, turning the fillets with tongs as needed.
Combine all ingredients in a non-reactive saucepan. Cover the pan and cook over medium heat until the sauce is reduced by half. Drizzle the sauce over the Stuffed Catfish.
Coat the asparagus spears with vegetable oil, salt, and pepper. Heat a medium skillet over medium-high heat. Saute the asparagus for a couple minutes until tender, rotating them with tongs, if necessary.
Slice the sweet potatoes lengthwise. Heat a grill pan over medium heat and add just enough vegetable oil to lightly coat the bottom of the pan. Add the sliced sweet potatoes to the hot pan in a single layer, and grill until they turn slightly crispy. Turn each slice with tongs and continue grilling until the second side is slightly crispy and the sweet potatoes are fully heated through. Season, to taste, with salt and pepper.
