How often do you grocery shop?

Hey everyone I’ve been vegetarian about a little over 2 months now. I don’t cook a lot so I use quite a bit of meat substitutes that I usually keep in the freezer unless I’m using them of course. The only thing I need to buy every week or two is fresh fruits and veggies so I was thinking about only shopping for quite a bit once a month. Also I only buy food for myself so little bags of things can go a long way. Does anyone else do this or how often do y’all shop?
