You might have skipped over that I also eat out decently often. Take out probably totals another $160-200 per month but a cost I can cut easily, a luxury. My Costco costs are maybe another $200 quarterly but still very possible without.

I was making 35k helping out people making under 17k do this up until a few years ago. This is not impossible to do. In fact, I do this without any coupons or deal searching. I use the member cards at Giant and HT, maybe a split decision at the store for the sale cuts or something but I could make this maybe $30 a week if I really got into it.

Just buy in season, in bulk if possible, know what things cost, have meals planned and eat with a purpose. I don't buy chips and soda and premade stuffs. I get treats for my partner all the time but I'm not one to snack. I try to eat healthy, I'm actually trying to lose weight believe it or not. It's just about the set up.
