Two of my favorites in the outlying area.
Casa De Tortilla - https://www.yelp.com/biz/la-casa-de-tortilla-somerset
Its kind of a love it or hate it place. Tex-Mex served by an Asian family. They make their own tortillas for the soft tacos and quesadillas.
Sappore Ravioli and cheese - Check out my HO post here: Sapore Ravioli & Cheese - Middlesex
If you want an italian style sandwich anywhere near new Brunswick or Piscataway, you should go here. I highly recommend the “Not so Chicken Little”
