I get by for 2 people on $50 per week in NJ near NYC by:
Shopping at Aldi
Going vegetarian unless eating out (rarely). Meat is very expensive, but many of my favorite produce is not much more expensive than before inflation started. We switched to egg whites from Costco instead of paying crazy prices for a dozen whole eggs.
Learning how to cook healthy. Spinach, red onions, tomatoes, bagged legumes, whole wheat pasta are all dirt cheap
