As for adding spice I would try finishing the pizza with some of this drizzled on top. https://www.amazon.com/dp/B00SXTB0AY/ref=cm_sw_r_cp_apa_glt_fabc_4Z42YMJGMPV8EPWM4JM6 It's a tomato based hot sauce, so goes really well with pizza (and everything really).
If you buy 2, you can save on shipping. Unfortunately a 2 pack costs $90. Just don't buy a 5 pack since that's $14 more than a 6 pack. Online prices (especially on Amazon) sometimes confuse me.
I used to be a Tapatio man until I discovered the aardvark
It’s the best for everyday use, I promise.
Here ya go 4.5lbs of it!

It's amazing. Get two bottles from Amazon for like 15 bucks or something. Worth it.
