In a pot add 1/2 cup of water and the chayotes (peeled and chopped in squares), cover, and steam for about 10 minutes in medium heat (same process if you are using potatoes)
In a pan add 1 teaspoon of vegetable oil, I am using avocado oil. Let it warm up, add then add garlic, saute for a few seconds, at medium heat. Add the onion and saute until the onion starts changing color.
Add the ground meat and on top the oregano, cumin, and salt.
With the cooking shovel, cut the meat into small pieces while it is cooking and mix together with the vegetables.
When the beef is medium-well or almost totally cook add the tomatoes, the poblano, and the chayote or potatoes.
Stir all together and then cover and let it steam all together for about 8 minutes or until the beef is completely cooked.
You can have the picadillo in tortillas like tacos or with some Mexican rice or even on top of a tostada with avocado!
