Rinse the rice under cold water until clear to remove excess starch.

In a medium saucepan, combine rinsed rice and milk; heat over medium, stirring until it simmers.

Stir in sugar, vanilla extract, and salt; reduce heat to low.

Simmer uncovered for 25-30 minutes, stirring frequently until thickened.

Gently fold in mixed berries and remove from heat.

Serve warm or chill in the refrigerator before enjoying.
