Seattle Mariners fans have more than warmed up to the newest, offbeat addition to the Safeco Field concessions menu: toasted grasshoppers covered in chili-lime salt.

The crunchy snack, which sells for $4 and comes packed in a small container, has only been available for less than a season but has already sold 300,000-plus orders to date. That's about 1000 pounds of grasshoppers. 

Frequenters of Seattle's popular Mexican restaurant Poquitos will know that this delicacy—which first started as a novelty item on its menu—has actually been available to the public for six years. But it wasn't until local chef Ethan Stowell was hired to give the Safeco Field menu a hip retooling that the salty bugs found new, fervent popularity at the ballpark. (Also on the Safeco menu: fried oysters drizzled in hot sauce.)

Great Big Story met up with Manny Arce, the executive chef of Poquitos and visionary behind this culinary home run, to discuss the popularity of these crunchy critters. You can watch the video interview below:
