Bring a large pot of water to boil. Scrub the potatoes and cut them into ½ inch thick strips and submerge in a large bowl of water until the boiling water is ready. Add the potatoes to the water gently with a large slotted spoon so it doesn't splash. The water won't boil immediately once the potatoes are submerged, but the moment the potatoes go in the water, set a 4 minute timer. Check to see if the potatoes have just started to soften but are not falling apart. Once they are just softening, drain the potatoes in a colander and let cool slightly until you can handle them.
Add the cooled potatoes to a large mixing bowl. Add the vegetable and olive oil and salt. Toss gently with your hands to coat.
Line two large baking sheets with parchment. Add your potatoes in an even layer on each, giving them space so they don't overcrowd each other. In a small bowl mix together the cumin, chili powder, oregano and cayenne. Sprinkle over the fries on each tray. Bake on two middle racks in the oven for 15 minutes. Stir each tray and then switch their positions in the oven. Bake another 20 minutes or until the fries are crisp and lightly browned.
Combine all the fries on one baking sheet. Top with the cheese and enough jalapenos to your liking. Bake in the middle of the oven for 3-5 minutes or until the cheese is soft and melted, but not browned. Remove from the oven and eat immediately.
