Step 1, throw them away
Step 2, grill some meat
Okay...I got my Ron Swanson joke out of the way early, so now I'll provide my serious answer lol.
I'm not vegan/vegetarian, however, I have given up 99% of my bovine animal product consumption (for environmental reasons) and for a while was trying a bunch of different thing to fill in the void.
I tried 3 or 4 different store bought soy patties
2 or 3 veggie patties
I tried the ones made from pea product (the Beyond Burger and the Beast Burgers)
It's going to depend on what your expectations are. I have friends who are vegetarian and vegan and got a lot of the 'try this one, you can't even tell it's not a real burger'...if someone ever tells you that, they're lying lol.
I did find a few Black Bean burgers that I would describe as edible...however, not exactly something I'd go out of my way to get.
