I've noticed some excellent frozen / refrigerated prepared foods. They have improved over the years in flavor and variety. When you compute the cost of preparing them yourself, both the ingredients and the time, it's a no brainer. Of course, i would love freshly prepared, homemade foods all the time, but that is unrealistic.
For example, Costco's Kirkland sausage and beef lasagne is about $13 and serves 6. I love the flavor, the tomato sauce, the different and generous cheeses, and the hearty meat. That is about $2.25/serving. It would take me at least 4 hours to market for, prepare, and clean up after making a lasagne. How can you beat that?
Other prepared foods I enjoy: Huxtables baked ziti with meatballs (also from Costco), Michaelangelo's eggplant Parmesan, TJ's tortellini with red pepper pesto. Have you found frozen / refrigerated prepared foods that you feel similarly about? Please share!
