[TOMT] [MOVIE] Early 2000’s movie about alien gems in a backyard

There’s this old live action kids movie about kids playing in their backyards and they find gemstones and diamonds and such then they find out they’re alien from outer space and the government is trying to find them so they run away with the gems.

One detail I particularly remember is a girl being vegan and there way this scene all eating burgers and a boy points out that the burger isn’t vegan so she spits it out that’s all I remember. I think the kids’ parents are running away with them too. Please help!
