Another simple option is a potato/veggie pan:
Depending on number of people, take some potatoes, cut to 1/2 inch cubes, cut whatever vegetables you like (we use bell pepper, mushrooms, zucchini, squash, etc) into similar sized cubes, roughly chopped onion, maybe a finger length of chorrizo sausage cut in small pieces, some fresh garlic.
Start with the potatoes in a hot pan with some oil, add the veggies depending on how fast they cook, I normally start with the potatoes, then one after the other onion, mushrooms, sausage, bell pepper, garlic, etc.; add some sweet paprica powder (stir right away), fry until mostly done, season with pepper and chili flakes, maybe add some dried herbs to taste (I use Italian Seasoning for simplicity). Mix well, let it cook maybe for another minute. Done.
This one requires more chopping and preparing, but it's simple enough and cleans up well.
If you have some sticking in the skottle or pan, just de-glaze with a bit of water and scrub quickly with a bamboo brush, done.
There is so much more that's easy ... I use mostly "one pan recipes", works great, not too much to clean up, and always tasty. I cook either in carbon steel or cast iron pans. Don't want to bring a skottle when I already need the stove anyways for coffee, noodles, rice, etc.
