This doesn't really need a recipe since it's not really from scratch, but I wrote up a post so I can remember how much stuff I put into a serving for one.
Preheat the oven to 375°F.
3.4 oz. of chicken breast tenders, cut into thin strips and seasoned with salt and freshly ground black pepper.
Lightly brown in a sauté pan. When fully cooked, season with a little cayenne pepper, about 1.0 oz. of canned enchilada sauce (I used Old El Paso, hot), and a tablespoon or two of hot diced fire-roasted green chiles.
Add the filling and some cheese. I used a nacho/taco cheese grated cheese mixture.
Bake uncovered for 15 minutes at 375°F until the sauce is hot and the cheese melted.
The trickiest thing is getting them out of the pan! I ended up tilting the pan over my serving plate and attempted to slide them out, which was only partially successful.
Update 11/3/2012: I tried putting the enchiladas in parchment paper slings. It works great!
Put the plate close by and lift the enchilada by its sling and put it on the plate. The only problem is that the sauce will want to run out the ends of the sling so do it quickly, and level.
Then just use a big spatula to slide it off the parchment paper. Since
you're just sliding it, as opposed to slipping the spatula underneath it
to lift it, the enchilada doesn't want to flip over when you plate it.
Perfect!
Also, I reduced the serving size from 2 enchiladas to 1, since 2 seemed like too much.

Update 1/4/2013: I made this again with grilled chicken and a batch of salsa fresca. I put a little salsa fresca inside the enchilada.

And put a little on top after plating:

The rest I served with tortilla chips. It was delicious!
Update 5/16/2013: Instead of messing with the separate pan and/or parchment paper sling, this time I just baked it on my plate, 10 minutes at 375°F. Obviously this should only be done with an oven-safe plate! To serve it, I set the hot plate on a not hot plate; the two layers make it possible to carry and not damage the table. I do the same for nachos.
Also, I measured the shredded cheese and I used 0.5 oz., with about half inside and half on top. And I used the whole 3.0 oz. package of grilled chicken to make one big enchilada instead of two smaller ones.
