Concepts
My concept of combining FB / IG post & stories with relatively the same amount of work. This was a 2 hour job but I had to source the assets.
You could also have the “story” as the left side of the FB/IG post and a sponsor (Heinz) as the right.
I took a post from The Depot and made a couple of tweaks. Reframed the food photo, opened up the text graphics over the image and, most importantly, made adjustments to the food photo to make the food more inviting. In all, about 2 minutes of work on the photo adjustments.

My graphics, their food photo. Brighter and better balanced graphics.
