Welcome to the forum. Sounds like you got a good rig. What Do you normally use in your kitchen? Start with a few and adjust from there. You will learn every time you use the camper. I have a large and medium sized frying pan, a large stock pot and collapsable strainer. Ziplock or Glad Plastic bags, large and small. That's what most leftovers go in for the night. Also get a pack of 2.5 gallon Glad ziplocks. They will come in handi for food and other things.
I always tell friends to go to the Goodwill, or thrift/second hand stores. If its in good condition, wash them once home and you're ready to go. If you damage the item, you didn't spend a lot. If later on you want newer/better you'll know what you need and want.
Depending on the trip and who I travel/camp with. I might pre-make some meals and just reheat once am set up.
Hope this helps and happy camping.
