Turkey Meatball Sandwich

Even though I haven't been posting about it, I'm still making tons of recipes I've pinned on Pinterest.  Last week I made a turkey meatball sandwich recipe that was incredible.  Granted, this is the first time I've ever made a meatball sandwich so I don't have much to compare to, but my husband, a meatball sandwich aficionado, agrees it's very good.

Some changes I made:
1.  I ended up purchasing no salt added crushed tomatoes so I added some salt to take out the blandness of the marinara sauce.
2.  Instead of feta, I used cotija cheese.  Didn't notice any difference and since we're moving, I'm trying to use what we have.
3.  I also bought pre-seasoned ground turkey but then still followed the recipe instructions on how to make the meatballs.  Made for some really flavorful meatballs!
