I really like the MealSquares. They aren’t quite right for replacing every meal, but are a heck of a lot better than most every-day quick meals. They are very tasty, and taste different depending on how you eat them.
My favorite way to eat them is to cut one into 9 cubes and throw it in the microwave for 25 seconds. Total prep time = 30 seconds. They come out evenly warm, soft, and the chocolate in them melts just a bit. In this form, I can’t quite describe the consistency, but it like a warmed dense date nut bread or banana bread. It doesn’t taste like that, but that is the consistency. With a few small chewy bits that I think are walnuts, but must be something else. Definitely not a fruit cake, maybe like a very dense multi-grain bread, but more dense than any multi-grain bread I’ve had. The flavor is very nice but I can’t directly compare it to anything else - orange juice, dates, chocolate, carrots, cinnamon, etc. When warmed, you get a slight sense of each of those tastes just a bit if you pause to think about it. If you just scarf them down with coffee, tea, or whatever your source of caffeine for breakfast, they are simply pleasing. Kinda a guilty pleasure, really.
The other way I eat them is directly from the fridge. In this form, they are more solid and dense. This is how I eat them when I’m driving in to work - as a whole square, biting off chunks. Because they are cool, they flavors aren’t “released” as much, and they are more bland. Not bland as in “yuck” but bland like a piece of bread - no taste jumps out at you, but if has a very dense, thick consistency that is very filling.
Another way to eat them is room temperature, which is half-way between the other two. Some people sprinkle cinnamon on them. I’ve heard of people putting jam on them, which seems a bit odd to me.
I really like the solid food convenience of them. Would be great for backpacking, although they do take up some space and are relatively heavy. I’ve lived on them 100% for three days straight and was never hungry - I find the solid, dense nature of them to be really satiating. I like that they rely on whole foods rather than vitamin powders for most of their nutrients. And absolutely no - zip, zero, none - problems with digestion, gas, or other physiological or psychological effects.
When I read other people talking about them, opinions vary, but everyone seems to have very positive comments when they try warming them up. I think that is the trick to make them appealing to people who compare them to “regular” foods. Compared to Solyent or mix alternatives - cold, room temp, or warmed are all a nice alternative.
