They'll eat your standard pork, chicken, beef, fish, seafood, etc. But they waste nothing.
For example, the ladies here particularly like to eat chicken feet. They believe that it has a high amount of collagen, which will help keep them looking young and lovely longer. They feed the chicken bones to their dogs who grind them up with their teeth and eat them. They will fry up the chicken skin like pork rind and use it for a snack with beer.
With fish, they'll take the parts not immediately eaten and they'll ferment it and make a sauce that they use in preparation of other food, like papaya salad (it's called bpla ra for those interested and, if you can get past the initial shock of the smell actually tastes pretty good)
Again, the ladies like to grill or fry the fish skin and eat it for the collagen.
People love to eat their prawns here (I'm sure you've heard of those huge Thai prawns). They not only eat the tails like we do, they'll eat the heads and suck the juice out of the little prawn legs like their drinking from a straw.
They'll dig up crabs out of the dirt from a rice field after the harvest and either pickle them or preserve them in salt and use them with other dishes.
And, well, they also eat bugs.
(Pictured:a stand selling all manner of bugs at our local night market)
And not every Thai person likes every bug and some don't care for any of them at all. For example, my wife likes crickets, but doesn't care for mealworms at all.
(FWIW, I think crickets would be OK, but they need some flavor. Maybe roasting them with some Old Bay would be good)
As for me, the only kind of bug I like are ant eggs:
You can prepare them by sauteing with some garlic and herbs and eat like a meat salad, cook them in a frittata or other ways. I would actually eat then more but, unless you are able to harvest them yourself they are bloody expensive.
Anyway, when I see Western hippies trying to inspire people to eat what they wouldn't ever eat normally just to virtue signal, it raises serious questions about their sanity and their morals. Nobody here eats what they eat in order to virtue signal. They eat because it was something their great grandparents had to do to survive...and because of that they were raised to enjoy it.
