For Pork Belly:
Season the belly with the salt, sugar and a sprinkle of pepper. Cover and let sit about 8 hours or overnight in the fridge.
Preheat oven to 450°F. Line a roasting pan with aluminum foil.
Cook at 450° for half an hour. Lower heat to 275° and cook for an additional hour or two. It should be tender but not mushy.
Remove from oven and let cool to room temp. Tightly wrap roasted pork belly in plastic wrap and refrigerate until chilled through. At least a few hours and up to a couple days.
When needed, slice into pieces of desired thickness and panfry in a drizzle of oil until brown.
For Salad:
About 10 minutes before serving, toss dressing with salad.
Sprinkle cranberry, pumpkin seeds, apple & walnuts over top.
Top with desired amount of pork belly and serve.
