Preheat oven to broil
Take the diced potatoes and place in small saucepan, cover with water and a dash of salt. Bring to boil. Keep an eye out until they are tender. I use a fork to do this. Drain and set aside.
While the potatoes are cooking do the rest of prep.
Take the can of chipoltes and chop 3 peppers. When the potatoes are done add sauce and the peppers to the potatoes and mix well. Take the 1/2 onion and mix with potatoes. You can adjust your heat level to what your preference is.
Use parchment and place on a baking sheet. Lay the tortillas out. Place the potato mixture on the tortillas. Add the green onions. Add the cheese. I mixed all these together with my hands because I like my nachos to be well covered.
Put nachos in oven and cook 5-10 minutes until cheese melted.
Top nachos with the tomato, green onions, cilantro. Dollop with sour cream and salsa.
