“Give them another try with onion, bacon, red pepper and a little vinegar for seasoning - mmm, mmm, go-o-od!”
If you have to put all of that in to make beans palatable, why not skip all the work of growing them and just eat the onion, bacon, red pepper and a little vinegar for seasoning?
A restaurant in my town serves them fried in a seasoned batter as an appetizer. They are absolutely delicious...
That’s just to bring the weak-kneed into the fold. Once you get em there, you can work toward butter, salt and pepper and, finally, right off the vine/bush.
