Use a sharp knife to trim the curved edges of 2 opposite sides of the flour tortillas to a 6-in width (Easy to do 3 at a time, makes spreading the ingredients a uniform process & makes slicing easy in equal segments). Set prepared tortillas aside & cover w/a slightly moistened kitchen towel or washcloth.
Mix cream cheese w/powdered sugar till well-combined & smooth. Divide mixture into 3 equal portions in separate bowls.
Add 3 tbsp strawberry preserves to the 1st bowl & mix well. Add 3 tbsp blueberry preserves to the 2nd bowl & mix well. Cut banana in sml pieces, add to the 3rd bowl & mash into cream cheese mixture till fully incorporated & smooth.
“Eyeball” the strawberry & blueberry mixtures for desired color. If a darker color is desired, add food coloring 1 drop at a time till you’re happy w/the color.
Assembly: Put 1 pre-cut tortilla on your work surface & spread 1/3 of the strawberry mixture over the tortilla surface. Place a 2nd tortilla 1-in to the right (keeping the end cuts lined up) & spread 1/3 of the banana mixture over the tortilla surface. Place a 3rd tortilla 1-in further to the right (lined up again) & spread 1/3 of the blueberry mixture over the tortilla surface.
Begin w/the tortilla flat on the work surface & roll them together into a circular log. The log will be fairly substantial in size & should be compact, but not so tight that your filling wants to “escape”. Wrap ea log snugly in foil or plastic wrap, so they do not come apart & their shape is retained. Repeat assembly steps w/rest of tortillas & ingredients. Refrigerate tortilla logs at least 2 hrs or put in your freezer for at least 1 hours.
Remove from refrigerator or freezer & cut logs immediately w/a very sharp knife into 3-in servings (6), 2-in servings (9) or 1-in pieces (18). Serve immediately or refrigerate covered in plastic wrap till ready to serve.
Serving Suggestion: Put on serving platter w/dish of cool whip & garnish w/banana slices + halved fresh strawberries & fresh blueberries. I bet kids would like a dish of red & blue M&M’s on the side too!
