A good soup for a cool fall/winter day. I like a bit of heat with the pork and lentils. It gives the soup a bit of character and really jacks up the warming effect of the soup. The soup would work just as well without the dried chilli peppers but I would use peppercorns to still provide a bit of warmth.
I used three different chillies here as I had them in on hand. You could just go with cayenne as they are more common.
