Preheat the oven to 400 degrees and line a baking sheet with parchment paper.
Add the potatoes to a stock pot and cover with water. Bring to a boil, lower heat and simmer for 15-20 minutes, or until the potatoes are fork tender. Drain and allow to cool for a couple minutes.
Add the potatoes to a bowl and mash until mostly smooth - it's ok if there are a few chunks. Add the salsa verde, dry seasonings and cream cheese. Mix until smooth, taste and adjust seasonings as needed.
Spray one side of a tortilla with oil. Flip it over and add a few tablespoons of the potato mixture. Gently fold in half so the tortilla sticks together. Place on the baking sheet and repeat with the remaining ingredients - my tortillas were on the larger side, so I made 8 big tacos.
Place in the oven and bake for 15 minutes. Flip and cook for another 5-10 minutes, or until your desired crispiness is reached.
Remove from the oven and serve with all of your favorite taco toppings.
