Dear Members,
Many Swaminarayan temples have food stores. It is 100% Vegeterian and they don't use onion garlic at all. So you will find lot of food items which are Jain.
Like Vegan Mayonnaise, Jain Pizza Sauce, Jain Pasta Sauce, cheese, etc and lot of varieties of snacks. You will find everything what you find in Indian grocery store like saffron soeap, toothpaste etc and also they keep Theplas, dhoklas during weekend. All these things are for sure there in Bay Area Swaminarayan temple.
I have attached photo of few items.
Regards,
Yash
