Alright Jet_Deck, I ordered a Mazzio's Works last night for delivery and had it with the Ken's Sauce. It's been years since I had a Ken's. Now I remember the sauce, and next time, I'll order just a cheese so spices from meat and veggies don't interfere in taste of the sauce.
After looking on line, I did manage to find this little bit of info regrading sauce. "And the sauce recipe includes fresh tomato tidbits and a blend of spices, giving it a bold flavor."

From the PM you sent me about the sauce and "the Zing", my initial thought is lemon juice not vinegar, but I do taste it. Spices I believe are basil, oregano and maybe ground anise seed, but never could get palette cleaned off good enough after eating the Italian Sausage. We'll get there.
