Even without new vegetarian options at grocery stores, I've been okay with cooking once a week for 2 or 3 hours. Breakfast is an egg casserole/quiche with veggies and chorizo spices or hashbrown. Lunch and dinner might be a lentil "meat"loaf, bean chili, or Indian style meals which are typically vegan. Lots of easy recipe options here, but it does help that I don't mind repeating meals for a week.
