Heat the olive oil in a skillet over a medium heat. Add the bacon and cook through until crisp and golden. Remove from the pan with a slotted spoon, leaving the fat behind and set to one side.
Step 2
Thinly slice the onion and add to the pan with the bacon fat, sweating for a minute to soften. Add the kale and pine nuts and pan fry for a few minutes until the kale is just wilted and the pine nuts golden.
Step 3
Add the pan fried kale to a large salad bowl. Slice the avocado and tear the bacon into bite sized pieces. Add to the bowl, season and toss to combine.
Step 4
Drizzle over the balsamic vinegar and sprinkle with the parmesan to serve.
