Has anyone used Huel? Supposedly you can make as much or as little as you want and they have some appealing flavors = green curry, mac and cheese, etc. Just add hot water. .... I guess

I never heard of them, at first it appeared that 3 meals were $75! I was LMAO until I found out in the fine print that there were 7 meals in each bag, thus you have to buy 3 bags and get 21 meals for a cost of $3.76 per meal. Assuming those meals are filling after being on a bike all day, then that's a good deal. Problem with this sort of stuff is that if you're touring you can't take 3 months' worth of food with you, in fact you wouldn't even be able to carry 3 bags, not sure how big those bags are but probably at the very most you could carry is 1 bag or 7 days of dinner only meals, or 3.5 days of lunch and dinner. So once you run out, you'll have to go to a store and buy food, so you might as well go on YouTube University and find out how to eat backpacking food cheap by shopping grocery stores because you're going to end up in a grocery store having to buy that sort of food.
I also noticed Huel was plant-based protein, some people, like myself, cannot extract enough protein from plants to sustain themselves and will be always low on energy. I tried a vegan diet when I was racing years ago for about 6 months, it was the worst 6 months for energy I ever had, even after our vegan expert friend tweaked it to increase the protein, I still was very low on energy, once we got off the diet my energy levels went back to normal.
The other thing is that Huel is high in fiber, some people will get diarrhea from too high of fiber, not something you want to deal with while touring. I'm not sure if what their using is too high or not, but remember, everyone is different, what's fine with one person could be too high for the next. In addition to that they use a lot of hot spice, probably in an attempt to cover up the nasty taste that their food has on their own without spice, but those spices can cause diarrhea in some people as well, as does curry and coconut have that potential. So, you have a quadruple whammy for diarrhea potential. So, you would need to buy it and try all the meals BEFORE you go on a trip so you will know whether or not they would make you sick. Even too much energy drink while cycling like when touring can cause diarrhea issues.
I think you need to learn what to get at a grocery store since that's where you'll end up pretty quickly into a tour, and start your tours with that same food without buying special camping food. Always try out food and drink before going on a tour, especially camping specific foods, and energy drinks, and when trying it out ride your bike for a 5 or so hours like you would do touring except you would circle back home, then eat and drink that stuff and see what happens.
Regardless, you should always carry Imodium AD as part of your emergency stuff, just in case.
