This is a creamy and luscious casserole. I used kabocha squash, which is sweet and softens up perfectly, and large poblanos, which were quite spicy. They can vary in heat. I'd cut back on the amount of poblano next time, as the dish was a little too spicy, but still delicious. Served with Ina Garten's Lemon Chicken Breast and a green salad. Will make this again.
