1In a large bowl, mix ground chicken (uncooked), refried beans and 1 1/2 cups shredded Monterrey pepper jack cheese and taco seasoning until well blended.
Fill uncooked manicotti shells with meat mixture using a butter knife or by gently pressing shell into the meat until the shell fills. Pour 1/4 of the green enchilada sauce into the bottom of a large baking dish. Lay shells in single layer on top of enchilada sauce. Pour remaining sauce over manicotti shells. Add 1 cup warm water around the edges of dish. Top with remaining cheese. Bake in 350 degree oven for 1 hour. Remove from oven and top with more cheese if you like and return to oven until cheese melts. Top with sour cream, sliced black olives and salsa verde. Enjoy!
