Used 5.5oz of shells, which was enough. Added a couple of large handfuls of spinach when I took the tomatoes out of the oven. 11/18/23 Very simple and nummy
12/15/23 Made w/ground turkey. No tomato paste; used fish sauce (1 TB) instead for the umami. 1/3 C shredded cheddar and a TB or two of blue cheese crumbles. Very quick and surprisingly tasty.
