I found this Chanko Nabe (sumo wrestler food) recipe from Alan Thrall (pretty good stuff on his channel)

It looked super tasty. I ran the macros for the whole meal and here is what it breaks down to:
cal = 4783
carb = 469g
fat = 266g
protein = 590g
Maybe I'll make a pot of it next week and break it up into individual servings. I think if I ate the whole thing I'd pass out.
