Halved grape tomatoes bring sweetness and color to many dishes, including the bacon-studded Canlis salad, from the Seattle restaurant of the same name. Slicing the tiny orbs, however, can be time-consuming. So, instead of halving them individually, we use the following restaurant trick to slice a dozen in the time it would normally take to slice one.
1. Arrange grape tomatoes on their sides so that they're arrayed snugly in the top of the shallow plastic lid of a takeout container.
2. Place another, identical lid, upside down, over the tomatoes; hold the top lid down firmly. Using smooth, strong horizontal motions, pass the knife between the lids, slicing through the tomatoes as you go.
3. Remove the top lid and, voila, your work is done.
