Answer:
Simplifying this problem we can think of this as a small industry or even a small shop.
Improving the pizza-making technology may improve the cost-benefit on making pizzas (by needing less time/resources to make each pizza for example) Now, thanks to this technology, there is a monetary benefit for the product. Now, with more money/time in the hands of the producers, they can invest it in the production of the other good (in this case the chicken wings). So thanks to the technology, they saved time and money that the inputted in the production of the wings, in this way increasing the wings production.
