The Cheeseboy franchise, with one of its nine locations in Milford, expects to hit one million grilled cheese sandwiches sold this week.

As part of the one million celebration, owner Michael Inwald is offering a lifetime of grilled cheese sandwiches and $10,000 to help one grilled cheese fanatic make an impact in the world.

Inwald is the founder and president of Boston-based Cheeseboy, America’s first grilled cheese franchise chain.

Since starting the concept in 2009 at state fairs, Inwald has grown Cheeseboy into a profitable business, currently with nine locations in the northeast, including Milford.

At 32 years old, Inwald’s secret to success is all about staying true to the classic grilled cheese sandwich and giving back to the communities in which Cheeseboy operates, a company spokesman said.

With competing grilled cheese concepts popping up all across the country ranging from food trucks to fancy, gourmet cheese shops, Cheeseboy officials say they stand out by staying true to the classic all-American comfort food and also giving back to the causes its customers and team members care about.

In April Cheeseboy gave away nearly 40,000 free sandwiches to people demonstrating acts of kindness throughout the northeast, and each year the company pays for its team members to volunteer at SeriousFun Camps, a nationally recognized camp for children with serious or terminal diseases.

Now through Saturday, Aug. 31, grilled cheese fans can answer the question, “What would you do for one million grilled cheese sandwiches?” in 200 words or less at GrilledCheeseForLife.com.

All responses must demonstrate how the respondent would use $10,000 to help make an impact in the world. Cheeseboy will make one participant’s dream a reality by providing a $10,000 donation toward the winner’s charitable initiative and honor that person with free grilled cheese sandwiches for life.

“Making a positive social impact and providing comfort to others in need are principles that I personally value, and they are pillars on which Cheeseboy was founded,” said Inwald. “In an effort to continue the spirit of giving as we celebrate Cheeseboy’s continued growth, I look forward to hearing what our fans would do to help make a difference in the world.”

Entries will be judged on their creativity in response, appropriateness, and viability of their charitable initiative. One grand-prize winner and five runners-up will be selected by Cheeseboy’s executive team.

The grand-prize winner will see $10,000 donated toward their charitable initiative and receive a Cheeseboy Rewards Card valid for one grilled cheese sandwich per week for life. The five runners-up will each receive a Cheeseboy Rewards Card valid for one grilled cheese sandwich per month for a year.

The Milford Cheeseboy is located in the I-95 Southbound service plaza. Before that, the eatery was at the Milford mall.
