To make any meal preparation easy it's good to have a Campsite Cooking and Clean-up Kit as part of your camping gear.
You want to ensure your campsite has the essentials for cooking your campout meals.
A couple of large plastic boxes with fold-over lids from the local Walmart will do nicely to store your cooking and clean-up accessories.
This is what to pack in one box:

• Pots and pans that fit inside of each other to save space
• A non-stick frying pan
• A metal and a plastic spatula/flipper
• Cutting board, knife and fork
• Can opener
• A mixing wisk
• Aluminum foil
• Eating Utensils - the hard plastic washable kind and of course lots of disposable ones
• Lots of cups - the hard plastic washable kind and disposable ones too
• Matches and a couple camping lighters
• Paper towels and plastic bags (for leftovers and to wrap food in)
• Spices (salt, pepper, garlic salt, etc.
  )
• Instant coffee and hot chocolate
• Some spare food - like a couple of packages of Macaroni and Cheese and a can of Ravioli, just in case you run out of food or for emergencies
• Plates and bowls (hard plastic and paper)

Pack these items in the second box: Camping gear for cooking over a fire:

• Old newspaper
• Kindling or fire starters
• Campfire tripod or grill to place over the fire
• Barbecue cleaning equipment

To keep your campsite clean and your cooking materials sanitary, these clean-up items are essential:

• 2 buckets (that fit inside each other) or 2 plastic tubs (that fit inside each other) for washing and rinsing dishes
• Dish Rags and towels
• Scouring pads
• Disposable wipes
• Detergent
• Plastic storage bags
• Trash bags

These are many of the camping gear essential items you might need for your Campsite Cooking and Clean-up Kit.
There will be additional items you wish to have, but try to keep your list to essential items only.
