Having lived in Texas for many years I am an avid eater of pinto beans. I tried this brand, linked below, yesterday and I am here to tell you they are both the best and the cheapest. I had been buying my pintos from Villa in Bangkok but they just keep raising the price and it is clear the beans are a bit old.
I finally went looking on Lazada and this brand claims to be both organic and grown in Thailand, I don't know if that is true but they cooked up real nice at half the price of Villa! https://shorturl.at/9LgNs
I have to say the many clearly bogus reviews of the beans on Lazada did give me pause, but the proof was in the beans.
