Rinse squash and with a sharp knife carefully cut off ends. Cut squash into 1 inch rings. With a knife or spoon deseed rings. (see Questions about spaghetti squash answered section above for optional step to reduce water amounts in squash) Place rings on a parchment covered cookie sheet. Salt and pepper to taste. Bake in a 400℉ oven for 50-55 mins. Remove from oven and let cool. With a fork gently pull squash strands away from skin.
Meanwhile whisk together all ingredients for vinaigrette. Prepare veggies.
In each bowl add desired amounts of squash, tuna, feta, bell pepper, tomatoes, cucumber, onion, olives, parsley and vinaigrette.
