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
Not sure how little time you have in the morning, but you could get the big Soylent powder bags and make them yourself. I’ve never tried it with coffee/espresso shots, but I sometimes make one with berries.
