For the mayonnaise first soak the cashew for 2 to 3 hours and then blend them with 1 tbsp of lemon juice, salt, black pepper and oregano. You can add garlic if you like the pungency but otherwise too this tastes great and stays in refrigerator for 4 to 5 days.
For lightly saute (30 secs) all the vegetables in 1 tsp of olive oil and add in a big bowl. If you want you can add some raw onions too.
Take a small bowl and add the cashew mayo, salt, pepper, coriander leaves, olive oil, lemon juice and olive oil and mix well. If you want little sweetness then add honey too.
Mix the dressing in the salad and give it a toss and keep it covered in fridge for and hour. This allows the salad to marinate with the dressing and you get to enjoy the flavours well.
After an hour take it out of fridge and serve for breakfast or any meal.
