In a large mixing bowl, combine the chicken, mayonnaise, sour cream, heavy cream, bouillon, salt and pepper and sage.
Fold in the French cut greens beans and caramelized onions. Spread the mixture evenly into your dish.
Bake for 30 minutes. Remove and layer Swiss cheese over the hot chicken mixture. Evenly distribute the biscuit quarters and return to oven for 10 minutes, or until tops are lightly browned.
Allow to rest for 5-10 minutes before serving.

Notes
If you have beef bouillon cubes, grind them with a mortar and pestle or the back of a spoon.
