Add olive oil to a pan and heat. Add onions and cook 2-3 minutes. Add package of tempeh crumble.
Cook tempeh and onion mixture until it starts to crisp and is heated through.
Unroll both cans of crescent dough and separate unto 16 triangles. Put a ramekin in the center of a baking sheet. Arrange triangles in a ring around the ramekin so the short sides of the dough are touching the ramekin, overlapping slightly, and the pointed ends are facing out.
Spoon the tempeh mixture onto the ends of each triangle closest to the center. Add a cheese slice over each and then top with a pickle slice. Remove the ramekin and fold each triangle over and tuck it into the ring.
Brush the top with the oat milk and sesame seeds. Once assembled, bake for 12-15 minutes or until the top and sides are golden brown.
While it bakes, add ketchup, mustard, mayo, and diced pickles. Mix and set aside.
Cut the ring into pieces and serve the dish with the sauce.
Enjoy!
