I store mine in the fridge, but rather than wrapped in plastic, I place the cut side down on a small plate and store it in the fridge unwrapped. It stores just as well and is less messy (no overly wet plastic). Plus when I cut another slice, I just grab it off the plate and put it right back.

Usually the rest of the tomato just becomes a side for my sandwich. I can't stand refrigerated tomatoes so leftovers if they had to be stored in the fridge would probably just end up tossed.

If I have a couple of slices left, I just eat it. When I make things for a meal that I don't think will be great later (a green salad, for example) I make a point that I want that item finished. A teenager usually obliges.

They seem to keep fine for 12 hours or so plopped cut side down on a small plate - room temp. Certain times of the year a few tiny fruit flies might take an interest - in this case, cover with a bowl.

I put them cut-side down in a sandwich-size resealable container, like a ziplock or tupperware (or glass, which is the best). On the counter, though, never the fridge! Even a short time in the fridge makes the texture go to crap.

Leftover tomatoes? What are those?

I usually put mine in a small empty freezer container with a lid, as we have an abundance of those, cut side down, and leave it out on the counter.

I say think of it like an apple- just eat the other half! :)

slice it up, add a little salt and pepper, drizzle a little ranch on it and enjoy!

If you dont think you'll eat the remaining tomato later in the day, eat whatever is left as a side. I avoid refrigerating tomatoes at whatever cost.

according to the health code... sliced tomatoes should always go in the fridge. the moisture level of their exposed surface is a huge breeding ground for bacteria. but unless you're expecting a visit from the health inspector, do what you want.

Hmm, I like this question. I always either eat my leftover tomato or store it cut side down in the fridge too but I'd say neither is an ideal solution. I was hoping for some brilliant epiphany of a solution from someone here.

I'll be the lone person who admits to leaving a cut tomato, wrapped tightly in plastic wrap, on the counter for a day or two. Then I eat it. So far, so good. Never more than a couple of days, though.

Please put your cut tomatoes in the fridge. Whole are fine to leave out, but cut tomatoes are temperature sensitive food that must be refrigerated. It's a food safety and contamination issue.

My mother always placed a piece of plastic wrap (saran wrap) over her cut tomato and put it back on the windowsill. The tomatoes were always good...I suppose Mother knows best.

I have been able to store cut tomatoes for more than two days in the fridge successfully using one of those things made to store onions (the ones that look like onions). They keep the air as well as the light out without anything really touching the skin of the tomato and the tomato looks almost fresh whenever you need to go for seconds (or thirds). I got the onion thingy at the local bed bath & beyond (mainly for the huge red onions that are impossible to consume in one go), but I'm sure other stores might carry it.

I read somewhere last summer that the ideal way to store for more than a few hours was to put it in a plastic zipper bag with a paper towel (or small dish towel, if you have one) against the cut side. This is supposedly to help keep it from getting soggy and super mealy while in the fridge. I tried it a couple times and it seemed to work well, but I may not be the best judge - I don't particularly care for tomatoes plain, so mine were always on sandwiches or in sauces or such which may have hid the texture. And which is also why I end up with half a tomato. :p

cut side down on a plate left on the counter. many times i will use half one morning and then eat the other half the next morning. i can't taste the difference. soooo much better than in the fridge - that would be a waste of a half of tomato imo.
