To make pasta salad from scratch, you will need sliced olives, crumbled feta cheese, sliced cucumber, cooked fusilli pasta or any pasta shape of your choice, sliced cherry tomatoes and chopped basil leaves.  You will also need to make the salad dressing that will go with your pasta salad. Simply mix in a bowl some olive oil, lemon juice, white wine vinegar, salt, pepper and oregano. In a clean bowl, mix together your pasta, vegetables, dressing until everything is fully combined. Serve on its own or as a side dish.
