Drain the peaches well, pat dry, and chop into bite-size pieces.
Stir the cottage cheese with the peach gelatin until evenly tinted and combined.
Fold in the thawed whipped topping until the mixture looks light and fluffy.
Gently fold in peaches, mini marshmallows, coconut, pecans, and vanilla until just mixed.
Cover and chill at least 1 hour before serving. Give a quick stir and spoon into bowls.
