That’s a wet bean burrito where I come from. This website has taught me that there is no common terminology for Mexican food (and whatever Taco Bell is) in the US.
Apparently they’re phobic about terms like “wet” and “moist”, hence the use of “smothered”. I prefer “wet” myself, but what can we two do against so much resistance?
When I went to Google and typed in enchirito to see what its ingredients are, it listed “red sauce.” Made me wonder about the quote marks.
It’s a burrito that’s been enchilada-d. Hence the name.
I find that amusing from a linguistic standpoint, as an enchilada is something that itself has been en-chile-d. (If you use a sauce that is tomato, it’s an entomatada, which, honestly, a lot of these enchiladas seem to be.)
And “smothered” is a perfectly good descriptor and used for a number of dishes that are doused in a gravy of some sort (see: smothered pork chops, for instance.)
I just ate, but now I’m hungry!
Late November? Fuck it. That’s gonna be my Thanksgiving.
So how do they serve these, especially for carryout? I presume not wrapped in paper, like most Taco Bell offerings.
I, too, have a distinct memory of what the old-style enchirito tasted like. Looks like I gave up on a low-carb diet at the right time 
In the 1970s-1990s they were served in lidded plastic trays, like nachos bell grande are now. In the more recent past, they were served in hinged paper trays, like tostadas.
The really old school enchirito was served in an aluminum tray with a plastic lid crimped to the tray. It then evolved into hinged paper trays.
So I was just running an errand, driving by a Taco Bell, and remembered this thread. I thought, here is my chance to try my first enchirito in what, 30 years or more?
My anticipation was palpable as I pulled into the drive-in. Aaand…no enchirito yet! Not till Nov. 17. 
Yes, November 17 is clearly stated in the linked article title in the OP. I’ve said before, nobody seems to thoroughly read OPs. Obviously that includes me as well. A burrito Supreme and a couple crunchy tacos made a decent consolation prize.
But the Mexican pizza is back … to stay!
I did see the Mexican pizza on the menu, but I have no nostalgic memories of that. Not like the enchirito, which recalls 70s era Taco Bell for me as a kid. Besides, I already had pizza last night.
I remember the look, the taste, the smell, and the packaging from the 70s version. Something tells me I’m going to be disappointed.
Anyone else remember when Taco Bell had just six items? Taco, burrito, tostada, enchirito, Bell Burger, pintos 'n cheese, and tostada? I think the tacos were 39 cents.
Now sal de mi césped!
mmm
And they’d throw in a broken taco shell for you to eat the beans with. 2 of those and a Coke were often my lunch in high school.
I miss the taco salads
Frejoles! Which we called, Free Jollys, being young boys.
First they shrank the tortilla shell by 50%, then they dropped them altogether.
Bastards.
That is correct, it was a bigger corn tortilla than they used for anything else, probably why they got rid of it. Having to source in a specialty ingredient that only serves one menu item is so inimical to the Taco Hell ethos they simply could not let it stand lol.
I’m so old I remember them at 18 cents! I had permission to leave campus in middle school (I tutored at an elementary school nearby) so I’d stop by the Bell for two bean burritos with extra cheese and I’d have just enough left over for a candy bar at the supermarket on the way back to school. Fifty cent lunch money days, those will never come again I suspect!
