These can be smoothies, bars, drinks, supplements, etc.

Is there something specific you look for (ex. price, ingredients, specific nutrients etc.)?

Is there a brand you like / avoid (ex. soylent, huel, hol food, etc.)

Edit:

I definitely don't recommend fully replacing your diet with them. I know some people use them instead of other processed food / fast food / skipping meals entirely, and that's the use case I had in mind for myself
