First, remove the excess packaging.

Repackage, either into double-zip ziploc freezer bags used for freezer bag cooking or into assembled dry ingredients ready-to-cook with separate containers for wet ingredients and a separate bag for add-ons to minimize packaging and trash you really need to pack out.

Leave the wrappers on chocolate. There is no reason, however, to have practically everything else in the original container. Repackage.

Remember: Leave No Trace "Pack it in - Pack it out"

I would add: Please do not burn trash at the campsite. The plastic "bits" are an unsightly mess. The foil will not burn. The odor of food on the smoke and the remaining "bits" invite bears and other "critters" into the camp.

Unless the fire pit is already there, I suggest using a backpacking stove instead. There is much less mess all around and it is less likely to start a disastrous fire, like a grass fire or a forest fire.
