I made this last night with the following changes. 10 strips of regular
bacon instead of the pancetta, no cayenne and a small can of tomato sauce
with a sprinkle of Italian seasoning as I had no Marinara.

The beans must have been very fresh. At one hour, they were slightly
overcooked. I tasted for seasonings. Added black pepper. Tasted great! Added
the tomato sauce and... Not so great. Might taste better when I reheat it
tonight. I didn't eat any last night. Just tasted it.

Pretty sure if I make it again, I'll leave out the tomato.
