Fusilli with Roasted Cauliflower, Peppers and Arugula in a Mustard Tarragon Sauce

Roasted cauliflower is one of my favorite vegetables and here I have paired it with a creamy mustard tarragon sauce with roasted red peppers, arugula and pasta for a perfect side dish to any meal. You can easily make this into a main meal dinner with a little bit of grilled chicken, fish or beans.

Roasted vegetables are simple to prepare and almost always one of my weekly meal prep tasks. Roasting up a variety of vegetables that can be used in salads, as side dishes, added to pastas, soups or added to wraps is a great way to help you get those veggies on your plate!

A common question I get from some of my clients is do white vegetables have any nutritional value? The answer is yes! Cauliflower is a great source of both folate and vitamin B6 and is also a rich source of antioxidants or phytochemicals in particular isothiocyanates and indoles. Isothiocyanates and indoles have been suggested in research that they may help with suppressing the harmful effects of carcinogens in the body.

Roasting the cauliflower will help preserve some of its beneficial nutrients versus cooking in water where you can have nutrients being leached out into the cooking water. So do not shy away from white vegetables as they can offer an array of nutrients!

Arugula has a slight peppery taste and is a great source of beta carotene and folate. You often can find it raw in many salads. In this recipe the arugula is tossed in with the pasta at the end of cooking and will slightly wilt from the heat. Gently cooking or heating the arugula will help to increase the absorption of beta carotene in your body.

The mustard tarragon sauce is simple to make. While the cauliflower is roasting you simply mix together in a small saucepan the mustard, cornstarch and broth and cook for 10 minutes. The sauce is then added to the pasta along with the Parmesan cheese and tarragon.

I made this dish using the Flavis line of pastas. Flavis products are gluten free, low protein, low sodium, low potassium and low phosphorous. A great option for those with chronic kidney disease or celiac disease. Their pasta is also a great source of dietary fiber. To learn more about their products you can visit their website here.
