Tayahan is a type of grass which grows on peddy fields. Basically they are soft like kangkung. So last night dad went to peddy field and picked some of them. The next day i was thinking what to cook for lunch. After almost an hour thinking what to cook lastly i decided to cook tayahan with sambal tumis. The sambal i mixed with a tomato and onions. Mmmmm..it was really nice. I never tried it before but my try and error trial worked well LOL! Honestly it tasted like kangkung..mmmm really nice and i would love to make it again.
