They’re great on grilled cream cheese sandwiches.
My wife likes them added to cornbread.
They’re generally a fantastic accompaniment with barbecue of any stripe- they’re basically the mildly spicy equivalent of sliced dill pickles in that respect.
Tacos are a go-to for me- pretty much any sort of taco is improved by pickled sliced jalapenos.
They’re also a good choice if you’re making queso- you can throw some in with the ro-tel without it being particularly weird, or you can put them on the side.
And they’re a common addition in bloody maries.
I’ve had them chopped fine in ranch dressing- that’s also a good use of them.
I’ve used them in a lot of the items already listed here. And you’re in a mindset, for whatever reason, to do a quick and easy lunch by opening up a container of something and microwaving whatever the contents are (which I do more often than I should), jalapeno slices can add a little life to canned beef stew, canned soup, Ben’s 90-second rice pouches, a Lloyd’s pulled pork sandwich, and the like.
Also, put a few on an Arby’s gyro sandwich.
Vanilla Ice Cream. Sometimes I’ll chop several jalapeno slices up into little bits and make a milkshake. If you like that sweet and spicy thing. It’s mostly a vanilla shake but sometimes you’ll get a bit or two of the jalapeno for that spicy element.
Chop 'em up and add to hummus.
At first I read that as 'chop ‘em up and add to humans’.
I’ll once again push the best macaroni salad in the world. I have made this exactly (and I do mean exactly) as detailed in the recipe below and the results are really great. The jalapeno is skipped by some I share this with and I think it is a BIG mistake. The jalapeno are in the background in this recipe (very finely diced…you don’t see them unless you are looking for them) but they add something important to the overall dish. Not to be skipped.
Best macaroni salad ever (there is a link to a video of this in the recipe below…where I got this from and well worth watching):
EDIT: I guess these are not “slices” per the OP. Just jalapeno chopped up. For slices I would say many sandwiches benefit from them.
They should be added to cottage cheese. It’s a wonderful combination.
The pineapple crowd are sorely deluded.
Both sound pretty good, honestly. Salty cheese, spicy chiles, sweet fruit.
