I also did not use flax seed because I did not have it. I added a little bit of salsa to make it a little juicier and to give it a little kick. And, I sprinkled with Borden's Colby and Monterey Jack cheeses. Yum!
Made this last night for the fam and it was a big hit! I didn't have flax seed so I left those out, but I did add just a touch of cumin and chili powder for fun. I will definitely make this one again!
