No, no, no — what you're seeing isn't some crazy cucumber-carrot/cucumber-tomato hybrid. Which is unfortunate. (Cucatoes, anyone?) But these veggie snacks will still make guests do a double-take, which rarely happens to poor ol' crudités.
There are only a few steps to this easy hack: cut off the ends of the cucumber, clear out the middle with a metal tube or apple corer, and fill it with a peeled carrot, little cherry tomatoes, or both. Cut into slices and prepare to be known as the person who can make even a veggie plate look interesting. You badass, you.
