There is something about the separation of elements that really appeals to me. The naked spaghetti on one side, and ice crusted meatballs floating on top of red sauce on the other. Frozen meals tend to hold their tray shape when you pop them out creating a smooth outline for a meal that thawed would be quite a mess.
I am most fascinated by frozen foods that are considered traditional American classics. Blocks of vegetables, and dinners representing our favorite comfort foods. I always think back to the dawn of frozen food and picture people in the past eating comforting meals in front of their TV trays. I am also interested in people who cook food in bulk and then freeze it for later. I do it with pasta sauce, but haven't gone much further with the idea. Something to add to my future to-do list.
Don't forget about the $100 Amazon Gift Card Giveaway I have going on right now. You can find that blog post at this link.
