You are being asked to research the nutritional profile, history, production, distribution, and/or consumption of a specific American food item -- which is a task that could potentially lead in many different directions. The following resources are going to be your best bets for getting started:
One way to guide us through evaluating sources via laterial reading is the CRAAP Test. CRAAP is an acronym to help us remember each aspect of a source we should be investigating:

As a reminder, your source does not need to "pass" every aspect of the CRAAP test in order for it to still be found credible. In fact, there may be times you may determine that a source is not credible, but may still present important information (a counterargument, a different perspective, an view of how understanding has changed over time, etc) that still makes it relevant and useful for your project. That being said, for this particular assignment, your sources will need to "pass" the CRAAP test and be credible in order to help make your argument about your food.
For more information about assessing sources, you are invited to consult:
