Gardenburger is the brand name of a veggie burger. It originated in 1985 and is owned by the Kellogg Company.
The Gardenburger was developed by Paul Wenner around 1981 or 1982 in Wenner's vegetarian restaurant, The Gardenhouse, in Gresham, Oregon. The company was originally incorporated as Wholesome & Hearty Foods, Inc., in March 1985. Initial funding was given to founders Paul Wenner and Allyn Smaaland, as part of a venture capital investment program of Louisiana-Pacific Corp., whereby L-P took immediate controlling interest. A second round of venture capital financing was provided about a year later.
In 2005, Gardenburger filed for bankruptcy, though it continued operation by becoming privately held.
In 2006, Gardenburger announced that it had taken eggs out of all of its products except for one private-sourced item which now contains organic, cage-free eggs.
In 2006, the company changed its name back to Wholesome & Hearty Foods.
In 2007, the Kellogg Company purchased the Wholesome & Hearty Foods company, makers of the Gardenburger.
The original formula (recipe) for the Gardenburger is no longer produced, as a key seasoning stopped being manufactured in the late 1990s.
The company makes a variety of vegetarian and vegan products and meat substitutes. According to the company's website, the original Gardenburger is made from mushrooms, onions, brown rice, rolled oats, cheese, eggs, garlic and spices. Gardenburger is a registered trademark of the Wholesome and Hearty Foods Company a subsidiary of Kellogg Company.
