Once in awhile when I'm browsing the frozen aisle at Trader Joe's I'll pick-up a box of Dr. Praeger's Veggie Burgers. They're yummy and pretty healthy to boot. If you're curious the list of ingredients are: Carrot, Onion, Stringbeans, Soybeans, Zucchini, Oat Bran, Peas, Spinach, Expeller Pressed Canola Oil, Broccoli, Textured Soy Flour, Corn, Oat Fiber, Red Pepper, Arrowroot, Corn Meal, Corn Starch, Garlic, Salt, Parsley, Black Pepper, All Natural Vegetable Gum. As you see, the only real unknown ingredient is 'vegetable gum.'
With the veggie burger patty, I made a Mexican style sandwich with just a few key ingredients.
Toasted Sour dough bread (or whichever kind you prefer)
Dr. Praeger's California Veggie Burger
Mexican Cheese or Soy Cheese (there's a mixed kind you can get at TJ's)
See instructions on how to cook the burger from the box. I used the guacomole as a spread and loaded it with cilantro. Use it like you would lettuce :) It's really that easy.
