Welcome to the Healing Well Wrapped Club! It sounds as if you're doing great! The pizza craving will have to wait, since tomato is pretty acidic...give yourself a few weeks before attempting to recreate that tasty treat. My guess is that you could make a pretty good facsimile with well-toasted bread and a little sauce and cheese. The sub sandwiches are a little trickier. Still, if you look at allowed foods you'll see that toasted bread is fine, and deli turkey would certainly chew nicely.
You'll have to experiment. There is one thing you cannot deviate from...take very small bites and don't chew anything that hasn't chewed to a liquid consistency.
Congratulations! Glad to hear the walking has helped with the shoulder pain--it did for me as well.
