The Deep Dish Plate by MSR. Wide like a plate, deep like a bowl, these non-leaching polypropylene plates are safe for hot and cold meals. The variable sizes nest inside most MSR pots: Small nests inside 2.5L pot, Medium nests inside 3.3L pot and Large nests inside 4.3L pots.
This plates are very durable. Probably a little big to take backpacking but great for car camping. The only problem I have with them is that they don't pack very well if you have more than one. If you only need one than it is fine.
