Canyon Bakehouse, a Colorado-based gluten-free artisan bakery, is hosting a Sammie Smackdown campaign on social media. From July 20 to August 3, five popular gluten-free bloggers will create their tastiest sandwich ever to compete for fan votes. The blogger with the winning sandwich will receive a $5,000 donation to the charity of her choice.

During the two-week campaign, fans can vote once a day. If they sign up for Canyon’s newsletter or if they share the campaign via the Canyon Bakehouse website to their social pages, they will receive additional votes for their favorite sandwich. Fans will also be entered to win a year supply of Canyon products if they sign up for the newsletter.

Natasha Gildea (@thefeistykitchen) will compete for Kick Cancer Movement
