Heat the butter/oil until melty and just about to brown, then turn the heat down
Add the diced potatoes and kohlrabi, and get them all stirred up and coated.
Add salt and pepper and paprika and red pepper flakes and basil (if dried) (add basil later if fresh!) Add chorizo if using!
Shuffle regularly and cook until potatoes are just about ready. (By which we mean, almost caramelized around the edges)
Add the chopped arugula or kale, then the tomatoes and corn (staged so they fit in the pan more than anything) and cook until everything is bright, and thawed if need be.
If you're adding a fried egg, part the hash in the middle and crack the eggs into the gap!
Sprinkle the goat cheese over top and serve with baguette!
