Here’s a trick to cutting cherry tomatoes!
Step 1. Take cherry tomatoes out of container and place on a small plate. A saucer would work great.
Step 2. Place a second plate (the same size) on top of cherry tomatoes and slightly press down.
Step 3. Take your knife and cut through the opening between the two plates.
Step 4. Remove top plate.
Now your cherry tomatoes are evenly sliced in half.
