There's two clear trends shaping up in the world of fast food in 2019. One of those is the rapid growth of plant-based fast food items and the other is value menu donuts for breakfast.

While McDonald's beat out Dunkin' on value with their take on the donut giant's Donut Sticks, Taco Bell just trumped everybody else with their own rendition: $1 Churro Donuts.

Now testing in the Kansas City area, these donuts come with a unique ridged exterior and are coated in a cinnamon sugar. They're a larger take on the half-dozen Donut Fries/Sticks that McDonald's and Dunkin' have to offer, but come at a cheaper price: just $1. Currently, six McDonald's Donut Sticks costs $1.49, while five Dunkin' Donut Fries comes in at $2.

Considering that Taco Bell is the only chain amongst this trio to have a true dollar or Buck and Under menu, it's clear they already prioritize value. To beat McDonald's at the value menu game like Taco Bell just did, though, is something few are able to really pull off.

The Churro Donut right now is just a test, but when Taco Bell brings that nationwide, McDonald's, Dunkin', and anyone else that brings donuts to the table better be ready for some fierce competition.
