Rinse and scrub yams. Use a form to pierce the surface of each yam all over. Place the yams on a foil-lined baking sheet and bake for 60 minutes (or 30 minutes if using small yams) until fork tender. (Cooking time may vary based on the size of your yams.)
While the yams are cooking, prepare the coleslaw by mixing together the cabbage, mayonnaise, water, green 1/4 cup green onion, white onion, lemon juice, salt, and pepper in a mixing bowl until evenly combined. Refrigerate until ready to serve.
Once the yams are done, carefully remove them from the oven and allow to cool on a cutting board.
Place a large skillet over medium heat and sauté the chicken breasts in oil for 7 to 8 minutes per side until no longer pink. Add BBQ sauce to the skillet and stir to until chicken is coated. Remove from heat.
Assembly
Place 1/4 of the coleslaw on a plate.
If using large yams, slice each yam in half lengthwise. If using small yams, cut a slit down the top of the yam lengthwise and squeeze the ends toward the middle to open op the top of the yam. Place 1 small yam or 1 half large yam on top of the coleslaw, open/cut side up. Spoon 1/4 of the BBQ Chicken into the open yam.
Top each yam with 1/4 of the black beans, 1 tablespoons green onion and 1 tablespoons cilantro, if desired. Add sour cream on top and serve immediately.
