Cheap Eats in Irvine

Where are some good cheap eating options in Irvine? I've been living off of Costco's food court, McDonald's app, Wendy's app, and Panda Express. I recently learned about WholesomeChoice's spicy Mexican chicken from the Iranian(IDK why it's called Mexican chicken) food section of their food court which is a great deal. I've also been frequently going to Mistuwa's food court for years for Oyakodon, it's an okay deal but it's fairly priced. Anyone know some other options for cheap or at least fairly priced food in Irvine?
