Olive salad tomatoes lemon avocado nuts

Cut tomatoes into four parts. Peel the avocado and cut it in half. We take out the bone. Spread the avocado halves on slices, in a bowl, pour olive oil (2 tbsp.l.), sprinkle with lemon juice, salt, pepper, and send to the grill, heated to medium temperature. When the avocado is browned, take it out of the grill or oven, put the tomatoes on top. The other one. squeeze the lemon out of the bowl, and put the red onion into it, cut into thin half rings. Mix well. Add the remaining olive oil, season with salt and pepper. We put the onion in the gaps between the avocado and tomatoes, and pour a spoonful of the mixture left over from marinating the onion on top. Sprinkle all this with pine nuts, and then cover with grated Parmesan.
This salad is served with any meat as a side dish or just a spicy additive.
