Greens Powder Worth it?

I live in a very Northern community 4 hours north of the nearest reasonably priced groceries. We drive down once every 2 months load up a truck full of groceries and come back. My fiancée is great at making our fruits and vegetables stretch for as long as possible but eventually we run out and end up eating just meat, rice and noodles. I’m not asking the question because I want to be ultra healthy but more because I think we actually need something like this to get all the proper vitamins until our next trip. Does anyone have a similar experience or advice? Also any recommendations are also welcome.
