Be it soup or beer, food as weapons has been in the media lately.  That give me an idea..

Dangerous Food

2nd-level transmutation

Casting Time: 1 action
Range: Touch
Components: V, S, M (a piece of fruit)
Duration: eight hours

Five juicy pieces of fruit appear in your hand and are infused with magic for the duration. A creature can use its action to eat one peace of fruit. Eating a berry restores 1d4 hit point.

Alternatively, a piece of fruit can be used as a weapon.  You can make a melee or ranged attack up to 30 feet as an action.  You are considered proficient when you attack with the fruit. If it hits, the target takes 1d6 magic bludgeoning damage and all enemies engaged with the target make a Dexterity save or take 1d6 magic bludgeoning damage as well.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, increase the number of fruit pieces by 1 for each slot level above 2nd.
