I tried the McPlant, McDonald's meat-free burger, and I don't understand why American diners snubbed it

• McDonald's US boss says trials of the McPlant weren't successful stateside.
• But the meat-free burger is on menus elsewhere, including Germany, Portugal, and the UK.
• Here's how the UK's vegan version of the McPlant compares to a Quarter Pounder with Cheese.

Don't expect to see the McPlant returning to McDonald's menus in the US anytime soon.
