I made this dish last night but instead of going to all the work of individual paper packets, I put the layers into a dutch oven and proceeded with the oven cooking. It worked very well. It is not a dish that I would serve to guests but was great for the two of us. Very tasty, and I made it several hours ahead. The spaghetti soaked up most of the liquid but it was replaced as the fish and tomatoes/veggies cooked. It is a bit work intensive for summer. Thank goodness my husband is my sous chef.....he does most of the clean-up of dishes.
