Skewer the potatoes with the bacon, weaving the bacon around each potato chunk.
Grill the skewers over medium heat with a low flame to reduce flare ups. Cook for 20 - 25 minutes, until potatoes are charred and fork tender and the bacon is crisp.
While the skewers cook, add all the vinaigrette ingredients to a small bowl and whisk until combined.
Once the skewers have been cooked, remove the bacon and potatoes from the skewers. Cut the potatoes into bite size chunks and chop the bacon and place in a bowl. Add the thinly sliced onion.
Pour the prepared vinaigrette over the potato mixture and toss to coat. Serve and enjoy!
