The answer is to use a camp stove (outdoors) that allows you to boil water. From here, you can make pasta, tea, soup, etc. Or you can use the flame to scramble eggs or cook potatoes, for example.
But how do you start a fire for your camp stove if you don't have a lighter? Emergency magnesium fire starters are popular, but very few people know how to use them. (They own them but have never used them.)
In addition, using magnesium to initiate a fire with leaves, twigs or grass is very difficult. So in this latest PrepWithMike video, available at PrepWithMike.com, you'll learn how to make your own emergency fire starters using cotton balls and petroleum jelly that help you get an emergency fire going for survival / off grid purposes (obey all fire safety rules and regulations, see below, don't be the idiot who starts a wildfire...).
With these items in hand, you can easily start a small fire with a magnesium fire starter, then use grass, leaves, pine cones or other small items to get a small camp fire going (or use a rocket stove).
As a safety note, given the extreme fire hazard conditions now present in Western states, obviously take every precaution to limit the size of your fire and control the flames. Don't be the idiot who sets fire to another 50,000 acres like recently happened with a California "gender reveal" party gone bad...
It's always a good idea to have a bucket of water nearby in case you need to extinguish flames, and never leave fires unattended. Even in this video, you can see I had a fully charged fire extinguisher handy:

This video was filmed before the recent wildfires went crazy, by the way, and the entire focus of this video is for emergency survival and preparedness / off grid cooking.
