This homemade Jersey Mike’s oil and vinegar dressing is all about simplicity and bold flavor. The key is using high-quality extra virgin olive oil and red wine vinegar—don’t cut corners here, as they make all the difference in achieving that signature deli-style tang. Letting the mixture rest for 15–20 minutes before using allows the spices to bloom and deepen the overall flavor. Always shake the dressing just before use to re-emulsify the oil and vinegar for even distribution.
