Lay one tortilla on a flat surface and spread 2 tablespoons of peanut butter, or almond butter on the tortilla, leaving about ½-inch border all around.

Sprinkle ½ cup of berries over the peanut butter/ almond butter (leaving one inch of the peanut butter/ almond butter on one edge uncovered), and use a fork to gently crush the berries, mashing them into the peanut butter/ almond butter. Sprinkle any add-ins over the crushed fruit, and roll up the tortilla working towards the berry-free edge, and using the peanut butter/ almond butter to seal the wrap.

Slice the roll-up as you like.
