An apple is 50 calories and mostly sugar. Almonds are pretty good. Most people don't find eating sardines plain to be convenient or tasty. Soylent is fairly well balanced, plenty of people seem to think it tastes good enough (I think it's a bit chalky, but, ymmv) and it's reasonably enough priced and convenient. If you aren't cooking most of your meals, and if you struggle with tracking macros and your needs are statistically average, then Soylent is probably not a bad solution. I got a case for my sister when she was having trouble keeping weight on her and it helped her back on track nutritionally - anecdotal obviously.
