Any idea what this plant is?

My mom’s coworker gave her some seeds she had saved. I planted them a few months ago and this one is growing well. The problem is, they were either mislabeled or I forgot what I planted because I could’ve sworn I planted the seeds she had labeled “Malabar spinach” here but that’s definitely not what this is lol

She also gave cucamelon seeds and I could kind of see the gourd/fruit thing being an overgrown cucamelon (though I don’t know if they can even get that big) but the leaves don’t look like cucamelon leaves. Plus, from what I remember, I wasn’t able to get the cucamelons to germinate.

So, anyone know what this could be? Thanks in advance!
