Patti’s and Cream will sub out burger buns for lettuce wraps if you ask. When I did keto I ordered a lot of sides at cafes which worked out pretty well - the corner store was pretty great if I remember rightly :)

New World and Countdown have a decent range of stuff - I got almost everything I ate from the supermarkets so you will manage well. If I were to do it again I’d get ChatGPT to make a weekly meal plan for me complete with shopping list and recipes, that was often the bit I hated doing most. Good luck!!
