The colonel, most likely, would lose his mind over the recent news that KFC in Britain is experimenting with a vegetarian version of the founder's famous fried chicken.

You know, the top-secret Original Recipe chicken, the one with 11 herbs and spices that (reportedly) only two executives have access to at any one time.

As part of a countrywide campaign to slim down, KFC UK is heeding the new guidelines issued by Public Health England, which recommends that British adults consume only 400 calories at breakfast and 600 apiece at lunch and dinner.

KFC UK told the Daily Mirror, the British tabloid, that it plans to remove 20 percent of the calories "per serving" - which, remember, may be much smaller than your idea of a serving - by 2025. That's a year later than PHE's suggested deadline.

The menu revamp will apparently include a veggie interpretation of Col. Harland Sanders's chicken, Victoria Robertson, the head of food innovation for KFC UK and Ireland, told the Mirror. The faux-meat bird is expected to roll out later this year.

"We know any new menu and recipe changes will have to be just as tasty as today," Robertson told the Mirror. "It's a tricky challenge, because our fans absolutely love our Original Recipe chicken, and we won't be changing the Colonel's secret recipe of 11 herbs and spices."

The KFC experiment with faux fried chicken may be an earnest attempt to shrink the British waistline, but it also aligns with meatless items recently added to menus at McDonald's and White Castle, two prime competitors in the fast-food category.

Late last year, Mickey D's introduced the soybean-based McVegan burger to restaurants in Sweden and Finland, and in April, the White Castle chain rolled out a surprisingly meaty slider featuring a plant-based patty from Impossible Foods.
