And, I think, for the taste.
It's so delicious: lighter than red meat, fresh because of the carrots and crushed tomatoes, and slightly sweet from the brown sugar. I topped them off with provolone and put everything on toasted whole wheat buns. If there are any leftovers, they're tasty when thrown in with some rice and stirred up. Bon appetit!
I used the recipe from Everyday Food with no changes made to the ingredients and procedure. Out of sheer laziness, just follow their excellent directions for a trip to taste central!
