With just a handful of ingredients, minimal prep and mere minutes on the grill, you can have this sweet and salty onion and Swiss flatbread on the table in no time.
Be sure all of your ingredients are prepped and ready. Heat a grill to med/high heat and brush the onion slices with 1 Tbsp of olive oil. Season lightly with salt and pepper.
Grill the onions until softened and browned on both sides, flipping once. Remove to a plate. Brush the flatbread on both sides with 1 Tbsp of olive oil and sprinkle with salt and pepper.
Lay the flatbread on the grill and grill for 1-2 minutes. Remove the flatbread from the grill and top with the swiss cheese, onions, honey, and thyme. Season lightly with salt & pepper.
Turn off one side of the grill and leave the other side on med/high. Place the topped flatbreads on the cool side of the grill, close the top, and grill until the flatbread is golden and toasted.
