Well, if what you ask is a tautology the answer is almost obvious. Almost.

No, that's pretty much it. In comparison, Pizza Hut and Domino's have slightly better pizza, at a higher cost. Little Caesar's discovered that enough people (college students, in my experience) were willing to eat slightly worse quality pizza - that was larger, but at a slightly cheaper price. From memory, Domino's was $12 for a 14" pie, but Little Caesar's was $10 for two 10" pies, that weren't as tasty, but were "good value for the money"

They originally saved money by using a cardboard tray not a box, that had a paper sleeve over it to keep the pizza sanitary. They could get two pies in there for what it cost the bigger chains to deliver one.

Wealth is created when the value of inputs is less than what is paid for the final good or service. It's really as simple as that.

The fact that one person doesn't see value in a good or have a willingness to pay the asking price doesn't mean nothing is created. There exceptions however, but by and large people are free to pay whatever price for whatever good. Canned fresh air, little caesar's, art etc.
