Lentil salad with caramelised onion and goats cheese

This is my lentil salad, which I made up the other day and I've already made three times, I was thinking of something filling and healthy and came out with this, it can be served as a main dish.

Ingredients:
One sachet of ready made black lentils (I used Merchant gourmet puy lentils) or one tin of cooked lentils.
one portion of goats cheese (they serve 250gr, discs)
one jar of roasted red peppers (about 300gr drained)
one red onion
2 or 3 finely sliced spring onion (only the green part)
splash of balsamic vinegar
splash of olive oil
handful of capers
10 sliced cherry tomatoes
handful fresh chopped coriander
handful fresh chopped parsley
10-15 sliced black olives

Method:
First, we need to caramelise the onion, so, slice it and fry it in olive oil until it becomes translucid. Add a good splash of balsamic vinegar, and leave it to reduce at a low heat, until it becomes a syrupy mix. Reserve.In a salad bowl, mix the rest of the ingredients, you can stick the lentils in the microwave for 30 seconds, so they are a little warm, add the caramelised onion and crumble the goats cheese on the top. Add a splash of liquid gold (olive oil), and salt and pepper.
