Hi! Here's the recipe, this is the way I make it at home. Since I only cook for 2 or 3, this serves 4, more or less. I don't have any real amounts, so all is aproximate. If you have any questions, let me know!
*9 or 8" square, or round, glass or metal baking dish, at least 2" deep
*CORN tortillas, fresh if possible, if not, then from a package. (about 500gr)
*shredded, cooked, chicken breast meat, or alternately, pork. (I use 1 whole breast)
*red or green salsa, either homemade, or from a can. Get the best quality possible. (about 1/2 litre)( 2 c)
*shredded cheese: Monterrey Jack, Colby, or even Mozzarella. do NOT use Cheddar. (about 2 c)
*whole cream, do not use half-and-half, or, in a pinch, you could use a mixture of both. You don't want it too thin.
*vegetable oil (needed for the tortillas)
Have everything at hand, and heat the oven to medium, 300 - 350 °F (170°C)
If the tortillas are cold, start by heating them on a med-hot griddle. Wrap them in a tea-towel until you have enough heated up, you can heat more if necessary.
Meanwhile, in a pan. heat enough oil to cover the bottom, and once it's hot enough, bring the heat down to med (don't let the oil get TOO hot).
With tongs, pick up a tortilla, and pass it through the hot oil, turning to coat, but DO NOT let it fry. You just want to coat the tortilla with hot oil. Begin placing each tortilla in the baking dish, covering the bottom first. Sort of like lasagna. Now the fun begins: layer first the shredded meat, then some salsa, then cream and then cheese, then start over again with the tortillas coated in the hot oil, repeat 3 more times. End with cheese.
Put into oven, and heat through, more or less 30 min. The cheese with get all crisp and bubbly on top (the best part!). Let sit about 5-10 mins before serving.
