Chicken "Pot Pie"

My garlic cheddar biscuits make men weep.

I do not even know why we call this chicken pot pie. There are no pots. There is no pie. Instead, it's a chicken casserole kinda thing but with biscuits atop.

THE CHICKEN PART
1 tablespoon Butter
Enough Extra Virgin Olive Oil to sauté the onion until caramelized
1 whole Onion, Medium Sized Diced Fine
A whole bunch of chicken. I use about 1/2 of a pack of boneless breasts or 1/2 of what I end up with after boiling and deboning chicken quarters.
3 cloves Garlic, Minced
A thing of celery, minus the yellow middle, sliced.
About half a pack of carrots, sliced.
1 teaspoon Rosemary, Dried
1 teaspoon Sage
2/3 cup Flour
1 box-like container of Chicken Stock; I think it’s about 3 cups.
Halfish of a bag of frozen peas. So just under a pound?
