Preheat oven to 375º
In a large bowl, combine the frozen veggies, cheddar cheese, and chicken.
In a separate bowl, mix the cream cheese and the condensed soup. Add it to the chicken-veggie mixture.
Spread the crescent roll dough out on parchment paper and place that on a baking pan.
Leaving 3 inches in the middle, make cuts down the side of the dough an inch apart on both sides.
Spread the chicken-veggie-soup mixture down the middle of the dough. Take a strip of dough from one side and fold it over the middle mixture. The take a strip from the other side and fold it over the middle. Continue down the dough, alternating sides until it is completely folded over....making it look like a braid.
Pinch the ends of the dough to keep the filling inside while it bakes.
Bake for 20-25 minutes so that the top is nice and golden brown.
Let stand about 10 minutes before cutting into it.
