Preheat oven to 350 degrees.
Place flatbreads on a large baking sheet. Brush flatbreads with olive oil.
Mince red onion, sliced artichoke hearts and halve the cherry tomatoes. Spread evenly on the flatbreads. Sprinkle feta cheese around.
Bake flatbreads until they're lightly crispy, around 10 minutes.
Once removed from the oven, top the flatbreads with the baby arugula. Drizzle balsamic glaze and sprinkle sea salt on top.
Use a pizza cutter to slice the flatbread into 12 pieces. Enjoy!
