This one will definitely have a positive effect on your heart!

Chef Seamus Mullen (behind Tertulia restaurant in NYC) and chef Hugh Mangum (who owns the multiple Mighty Quinn's Barbecue) dropped by the kitchen to talk about a cause very dear to them — and Rachael: ending child hunger.

And to do it, they both cycled 300 miles!

As part of Chefs Cycle, Hugh explained to Rach a month before the race, "Seamus, myself and about 250-plus [275 total!] of our colleagues — chef friends — we're riding 300 miles in Santa Rosa, California, in May."

The ride was a 3-day tour starting May 15 and ending May 17 -- and it raised over $1.4M for No Kid Hungry.

What's more is that the next race starts on September 25 in Charlottesville, Virginia -- and so far, nearly $100,000 has been raised for it.

Amazing!

"The end game," he adds, "is that this problem — childhood hunger in America — it goes away. It's a solvable problem."

"It should be eradicated — well within our lifetimes," says Rachael.

Hugh agrees: "Especially in the country we live in."
