gringo sancocho, basic version:
season the meat. can be chicken, chivo, beef, chuletas, salchichas, whatever takes your fancy, really. leave to rest when you are off to prepare veggies. potatoes, yuka, banana (green), platano (green), rulo (green), yautia, carrots, squash, celery (root), corn (whole), whatever you like. peel, cut into chunks (i like bite size chunks, dominicans usueally make the pieces bigger), wash.
put meat into a big pot. i never bother to cook meats separately, sancocho is lots of work as it is. some olive oil (i love olive oil) and off you go, fry it. when meats gets some colour pour in water. cook.
give meat some time, it should be well cooked. add veggies. now, i sometimes cook vegetables separately from meat but i do not have a pot big enough to hold all the soup. you will see that even one piece of each kind of meat and one of each veggies will make LOTS of sancocho

in any case, let everything cook. now peel, clean and cut ayuama. can be bigger chunks, it cooks quickly anyways. throw auyama into the soup. add few pieces of garlic, a cut up onion or two, green celery (bush), parsley and coriander (if you are crazy

). when auyama gets softer fish it out along with herbs, onion, garlic, some carrots and quite some liquid. do not despair if you cannot find all auyama/onion

you are not in a competition.
blend whatever you fished out, add to the soup. it should be now thick and creamy. add salt, pepper, herbs, whatever.
since i hate rice and never ever eat it i serve my sancocho with aguacate only. there is enough veggies in it to make it a nice full meal.
ps, i normally do not eat meat but i make few exceptions. i will eat sancocho - liquid and vegetables - but not meat pieces. yes, i know, it is soaked in meat anyways.
