Vegan/Vegetarian staples

Me

Hey for those of y’all that are vegan or vegetarian what would you say are some things you like to always keep on hand? This is my second week of being vegetarian again and I feel better than I ever have and really want to make it last this time. I plan on going to Whole Foods to look for a few items to have on hand for quick meals when I don’t want to have to cook. Also what’s the best oil other than coconut oil to use for cooking?
