Heat oil in a large skillet over medium-high heat until shimmering. Season sirloin with salt and pepper on both sides. Cook until desired doneness, about 3-4 minutes per side for medium. Remove and let rest for 5 minutes to redistribute juices.

Slice the rested steak against the grain into thin strips, then cut into smaller, bite-sized pieces for easy eating in the quesadilla.

Heat a large skillet or griddle over medium heat, ensuring the surface is evenly heated and large enough to accommodate a folded tortilla.

Place one flour tortilla on the heated surface. On one half, sprinkle ¼ cup each of cheddar and Monterey Jack cheeses, plus one-quarter of the American cheese pieces. Add one-quarter of the sliced steak over the cheese. Spread approximately 1 tablespoon of jalapeño sauce on the empty half of the tortilla.

Fold the sauce-covered half over the cheese and steak half to form a half-moon. Cook until the bottom is golden brown and crispy, about 2-3 minutes. Flip carefully and cook the other side until golden and the cheese is completely melted, about 2 minutes more.

Transfer the cooked quesadilla to a cutting board. Repeat the process with remaining ingredients to make a total of 4 quesadillas. Let each rest for about 1 minute before cutting into triangular wedges. Serve immediately while hot and crispy.
