1-First step: prep all the vegetables. Start by getting everything ready before the skillet heats up. Peel and trim the carrot, then shred it using the large holes of a box grater. Thinly slice the red cabbage as finely as you can so it softens faster while cooking. Slice the red bell pepper and yellow bell pepper into thin strips, and roughly chop the cilantro leaves and tender stems. Keep the baby spinach close by so it is ready to layer in a flash.

2-Second step: grate the cheese. Shred the cheddar and Monterey Jack mixture if it is not already shredded. Freshly shredded cheese melts more smoothly than pre-shredded cheese, so if you have a few extra minutes, this small step is worth it. Set the cheese aside in a bowl so it is easy to grab as you build the quesadilla.

3-Third step: warm the skillet. Set a large skillet or nonstick pan over medium heat. Let it warm for about 1 minute, then add the first tortilla. You want the pan hot enough to crisp the tortilla, but not so hot that it burns before the cheese melts. If your stove runs hot, keep the heat on medium-low to medium.

4-Fourth step: layer the filling. Sprinkle about half of the cheese over one tortilla. Then add a handful of shredded carrot, a little red cabbage, some baby spinach, thin slices of both bell peppers, and a scatter of cilantro. Finish with the remaining cheese so the filling stays tucked together. Top with the second tortilla. This gives you a classic stuffed quesadilla shape, but if you prefer, you can fold one tortilla over the filling instead.

5-Fifth step: cook until golden. Cook the quesadilla for 2 to 3 minutes on the first side. Press it down gently with a spatula so the cheese starts melting and the filling settles into place. Check the bottom after 2 minutes. When it is golden brown and crisp, carefully flip the quesadilla using a wide spatula. Cook the second side for another 2 to 3 minutes until both sides are browned and the cheese is fully melted.

6-Sixth step: rest, slice, and serve. Move the cooked quesadilla to a cutting board and let it rest for about 1 minute. This short pause helps the cheese settle so the filling does not spill out when you slice it. Cut into wedges with a sharp knife or pizza cutter. Serve hot with sour cream and salsa on the side if you want a classic finish. The total cook time is usually about 15 minutes, and the whole recipe takes around 20 to 25 minutes from start to finish.
