I don't know which one might have avocado in it, but it isn't the California Burger. I tried to check out Dr. Praeger's website, but it's under construction.
Here's a review from Hungry Girl's website:
Dr. Praeger's Veggie Royale California Veggie Burgers
(100 calories, 3.3g fat, 190mg sodium, 9.5g carbs, 4g fiber, 0g sugars, 8g protein)
Overall Score: 9.5
Dr. Praeger makes the most delicious and unique veggie patties on this planet (possibly in the entire galaxy, though we haven't expanded our search that far yet). You can actually identify pieces of edamame, carrots, broccoli, corn and more in every bite. It's a cornucopia of veggie delights! And his nutritionals are right on. Low calorie, no saturated fats, lots of fiber, no sugars, not a lot of carbs -- what more could you want? The only less-than-glowing thing we can say about these delightful disks is the fact that they're a little harder to find than most other veggie burgers (look for 'em at Costco and Whole Foods, or buy 'em online). Despite that, they've earned a well-deserved 9.5.
