This is almost identical to one sold at a local sandwich shop here…
1 package vegetable noodles (3 colors)- cooked
1/2 small red onion- chopped
2 Avocados- cut into chunks
1 tomato- chopped
1/2 can olives (I didn’t use this time)
1/2 bottle of red wine & olive oil dressing (found with refrigerated dressings)

Mix all together!
