Actor Kal Penn, best-known for playing Kumar in the "Harold & Kumar" stoner comedy film series, has invested in the vegan Impossible Burger. Forbes reports that Penn first tried the plant-based burger created by vegan meat brand Impossible Foods\u00a0over a year ago, when he ordered it from the fast-casual restaurant, Bareburger. At first, the actor was so taken aback by the vegan burger's realistic flavor that he checked with his server to ensure that his order was correct. Penn later learned that a friend of his worked at Impossible Foods and quickly decided to become an investor. Penn\u00a0believes in Impossible Foods' mission of making\u00a0factory farming\u00a0obsolete.\u00a0"A lot of things are compartmentalized because we don\u2019t always have a chance to make conscious business decisions,"\u00a0he said.

The unprecedented move provoked the actor to reflect upon how his individual choices impact the planet, and as a result, he decided to remove meat from his plate.\u00a0"I thought, 'If I\u2019m really this angry, maybe I should start making better choices for myself,'"\u00a0he said. Penn, who now describes himself as an\u00a0"aspiring vegan,"\u00a0realized what many recent studies, including the largest-ever food production analysis, have confirmed: a plant-based diet is the most effective way to combat climate change. "I felt like this was in that vein,"\u00a0Penn continued, commenting on how his investment in Impossible Foods\u00a0goes hand-in-hand with his ethics.\u00a0"I had a chance as an investor but also a fan of the product. It\u2019s a company making a delicious product, making meat out of plants in a way that\u2019s more equitable for the planet, more green, and the fact that it\u2019s at White Castle makes the price point accessible to a lot of people." Earlier this month, after being tested at select White Castle locations, the vegan Impossible slider was added to the fast-food chain's menu nationwide. White Castle vice president Jamie Richardson agrees that this vegan burger can make an impact. During the test run, some White Castle locations reported selling as many as 300 meatless sliders per day. White Castle marketing head Kim Bartley credited the huge success, in\u00a0part, to the company's successful social media strategy. The "Harold & Kumar Go to White Castle" star has fully embraced the White Castle vegan Impossible Slider. Last week, he appeared in a social media ad on Impossible Foods' Instagram, encouraging followers to take part in the new campaign featuring members of the Wu-Tang Clan.
