I definitely didn't grow this!

So I'm watering my tomatoes today and I see this new sprout of something I've never seen before.
I'm completely sure I didn't plant this! (I potted the plants myself) Also, the plants are indoors at all times so how can a random thing sprout?

Can you figure out what it is?

It's leaf is round and thick.

it's a weed! A weed of course being anything that pops up where you didn't plant it and don't want it.

A little hard to tell yet what variety of weed, since those are just the cotyledons (seed leaves) which often are quite different than the true leaves (you remember the first two leaves your tomato seedling put out were just long and narrow and didn't look like the leaves it is making now).

The thick round seed leaves could be some kind of pea or bean, but it could be a lot of other things also.

So how did a weed pop up in your indoor plants? The seed could have been in the potting soil. I always get a few weeds in with my indoor started seedlings.

Thanks for explaining rainbowgardener!
This is so interesting!
I'm going to let it grow a bit. (I'm curious) I'll post a photo in a while so It can be identified.

Looks like a bean plant. You can tell after the cotyledons open. Like RBG, I usually get some seed in my purchased potting soil. This year, it is lettuce. I pull them while they are small, but they look like black seeded simpson seedlings. No big deal. I grew lettuce in a couple of beds last year. I didn't let any of it grow to seed, but I am still finding little lettuce seedlings growing in unusual places in my garden.
