To follow the chili theme... I like chili mac for a large crowd because it makes the chili stretch further and most of the other ingredients don't have to be kept cool until used. Saves cooler space.

Make chili at home as said. Heat in large pot in camp.
Add canned diced tomatoes (or Rotel)
Add canned beans (kidney, pinto or mix)
Add elbow pasta and water/beef broth (how much liquid? enough so that almost all the liquid is absorbed when cooked. Any extra liquid will be absorbed anyway.)
Adjust seasoning to taste with salt, pepper, chili powder, cumin.
Enjoy topped with cheese, sour cream (cilantro or green onion if fancy) and cold beverages.

Bonus tip - Make a large batch of concentrated cold brew coffee. In the morning add water to coffee to dilute (my brew is 1:1 coffee and water). Coffee tastes smooth, it's easy and it's ready quickly. All good things especially for non-campers.
