After we heard earlier this month that Taco Bell sold more than 100 million Doritos tacos in 10 weeks . . . which might make them the fastest-selling fast food item ever . . . we knew more varieties HAD to be on the way.  And they are.

A website called FoodBeast found two new varieties being live tested at six Taco Bells in Orange County, California.  The new flavors are shells made of COOL RANCH DORITOS, and of a spicier FLAMAS Doritos flavor.

No word on when these could go on sale nationwide.
