Ingredients for a Vegan Italian Pasta Salad

As with this summer veggie pasta salad, all cold pasta salads I've ever had growing up have been meat-free, but I guess some families make them with meats such as pepperoni and even include dairy like mozzarella. Not here! This one is all about the gluten-free pasta, veggies, and homemade Italian dressing!

Gluten-Free Tri-Color Rotini (you can use plain gluten-free rotini too)
English Cucumber
Bell Peppers (1 red, 1 orange, 1 yellow)
Red Onion
Grape Tomatoes
Black Olives
Extra Virgin Olive Oil
Red Wine Vinegar
Dried Oregano, Basil, and Parsley
Salt & Black Pepper

This recipe serves a CROWD. Since it is no meat or dairy, it will last longer than other cold pasta salads. You can store it in the fridge for a week, making it a perfect side dish or even entree to meal prep! This way, if you don't have a crowd to feed all in one go, you can enjoy this gluten-free pasta salad as you need!

How to Make the Pasta Salad from Scratch

This is SUCH an easy recipe and so quick to make! It's just chopping up fresh veggies, boiling some gluten-free pasta, and tossing everything together in one BIG bowl!

Making the Homemade Italian Dressing

There's no need to dirty an extra bowl for this. Just measure out the olive oil, vinegar, and herbs and add them right into the pasta salad bowl. You can season to taste here with the herbs and spices you have on hand. Besides the parsley, oregano, and basil, some other flavors you can include:

Dried Rosemary
Dried Marjoram
Dried Thyme
Ground Sage
Minced Garlic
A squirt of Lemon Juice

The Best Way to Store and Serve Gluten-Free Italian Pasta Salad

Store the finished pasta salad in a covered bowl or container in the fridge for up to one week.
Let the pasta salad sit and chill for a minimum of 30 minutes in the fridge before serving. Ideally, let it sit overnight to really marinate!
Toss the pasta salad before serving to distribute all the dressing and flavors again. Serve it cold or bring it room temperature for optimal flavor.
Don't leave leftovers out of the fridge any more than an hour or 2 to prevent spoilage.

A Healthy Summer Side Dish for any BBQ or Cookout

Instructions

Boil the gluten-free rotini according to package directions, minus about 2 minutes to keep the noodles from getting mushy.
In the meantime, chop the bell peppers, cucumber, tomatoes, onion, and toss them into a large bowl with the sliced black olives.
Drain and rinse the pasta under cold water to stop the cooking process before adding them to the chopped veggies.
Measure and add the olive oil, vinegar, and seasonings to the pasta salad bowl.
Gently mix and toss everything together in the bowl to combine.
Let the pasta salad marinate and chill in the fridge, for at least 30 minutes (preferably overnight), before serving.
Enjoy cool, at room temperature.
