Ruby Tuesday's Basil Pesto Pasta Salad

My Father has fallen in love with this pasta salad they have on their salad bar. We had asked for the recipe, but unfortunately, they couldn't give us quanities but just gave us the ingredients. So what I did was bought the ingredients then played around until I got the dish to taste like their salad. Dad says it tastes exactly like it so I hope you enjoy!!

Made Basil Pesto first:

3 cloves of garlic
4 large sprigs of fresh basil
½ to 1 cup of parmesan cheese
2 tbsp slivered almonds
Olive oil to make a paste

Combine all ingredients in a food processor till pesto like consistency

For the pasta:
4.25 oz can of chopped black olives (they were already pre chopped)
2 roasted red peppers (marinated in water only, not pickled in vinegar and not marinated in olive oil), chopped very fine
1 pkg of feta cheese
1/3 of a Vidalia onion, chopped very finely
7 leaves of fresh spinach chiffonade cut
Salt and pepper to taste
½ pound of spaghetti, broken into threes before cooking

For the dressing:

2 tbsp of the basil pesto
3/4 cup of vegetable oil

Whisk together the vegetable oil and the basil pesto together. Mix together all of the ingredients and pour the dressing over it. Let stand to meld the ingredients together.
