When we go away camping, we menu plan and I try and pack pantry items we'll need instead of buying while we are away. Why buy sweet chiil sauce when you can pack the 1/4 cup you'll need? Vegetable stock, rice, palm sugar, sesame oil, fish sauce, peanuts, all packaged ready to go.
I've made up spice and herb mixes for roast lamb, bbq steak, pork skewers, lamb kebabs and thai green curry. I've already packed pasta and sauce for bow-tie bolognese, we just need to buy meat and fresh veggies.
