If you want to save money on food you are going to have to get familiar with food trends and look at the new recipes that are surfacing. This is the most common way to take things that may have been in your cabinet and actually make new meals that you did not realize you had the capability to make.
In metropolitan areas these food trends are called food hacks. The reality is that most hot new food trends are things that people have experimented with. It was something that they may have assumed was going to taste good with certain ingredients so someone tried it. Once they had success they decided to let someone else tried. When someone else got a chance to try and confirm that it was tasty this experimental cook would move down the line. They would let others taste it. If they had a restaurant or a food truck they would present this as a new item on the menu. That is how most food trends become mainstream meals. Someone was bold enough to try and experiment on something that had not been tried before. The end result led to something successful.
The funny thing about food trends is that not all of these trends tend to take off. It has been reported in the past that Taco Bell goes through hundreds of different ideas for menu items each year. Throughout the course of the year there may be less than 50 of these items that will actually be introduced to the public on the menu. This is a large amount of brainstorming just to come up with a few menu item changes.
Realistically, America is fickle nation that thrives on food trends. People that were in love with a certain type of burger or salad yesterday maybe looking for something completely different to consume today. People in positions of leadership in restaurants must consider how food trends can change menus overnight.
