From The Vegetarian 5-Ingredient Gourmet, by Nava Atlas.
Leeks and carrots both have a natural sweetness that mingles nicely.
This is a mild and pleasant side dish, good with pasta, potatoes, and soy dishes.
We loved this dish.
I make these and double the recipe.
I wrap each burger and lay on a cookie sheet till frozen then bag, they keep in the freezer about 3 months. It's a great recipe for when ground chicken or turkey is on sale.
