I bought an assorted six pack of these a while back. Thought they would come in handy for 'emergency' food on the go - on the rib/road trips etc. Keep one in the rib, one in the car, one in my backpack etc.
After seeing this thread, thought I'd try one out at work since I wouldn't be getting a hot dinner today! Tried the All Day Breakfast. Used double the water pouch (emptied pouch then filled it again to measure) after reading the comments. Wrapped it in a cloth then left it 15 minutes and it was roasty toasty.
It was piping hot, but well evenly cooked, beans weren't burnt at all. Actually quite surprised at how well it cooked and how hot it was. Taste wise, It's slightly better than the canned variety. Certainly did the trick and looking forward to trying the chicken casserole!
I'd definitely recommend them. Got mine from Amazon
