Never had that particular brand, but you get the idea.

Frozen grapes. Once they’ve been out of the freezer for a couple minutes, they thaw into little slushie bubbles.

Does air popped corn count as low calorie? If not, it’s gherkins for me

Carrots cut into thin planks to scoop home made salsa verde

Fridge cold honeydew melon. Nothing even closely compares to how tasty that is for me. Low in calories as well.

sugar snap peas go crazy, and they’re very filling too
