2 cans (10.5 oz each) Cream of Chicken Soup: This provides the salty, savory base and the creamy texture you loved.
2 to 3 cups Cooked Chicken: Usually rotisserie chicken or leftovers, chopped into bite-sized chunks.
1 bag (12 oz) Frozen Mixed Vegetables: (Optional, but usually hidden in there!) If she kept it strictly to 4 items, she may have swapped the veggies for an extra splash of Milk or Sour Cream to make it even richer.
1 can (16.3 oz) Refrigerated Flaky Layers Biscuits: This is the “game changer” secret for that bubbly, browned top.
