A filling, gluten-free salad which is healthy and makes a great lunch for your work.
You can use apple cider vinegar
instead of lemon juice.
You don't have to use all the ingredients, you could simplify the salad and skip mushrooms or any other ingredients.
If you don't have pickled mushrooms you could simply slice and fry some mushrooms quickly.
To get all the flavours to come together leave the salad in the fridge for at least 30 minutes before serving.
