Dice your onion, potatoes, and carrots into small cubes and pieces. The smaller the better because it will cook faster.
1 cup yellow potatoes, ½ cup carrots, ¼ cup onion
In a medium saucepan on your stove top, add vegetables with 1 cup of water. Bring to boil, cover, and turn down to simmer for 8-10 minutes until potatoes and carrots are fork-tender.
1 cup water
While veggies are simmering, in small saucepan begin heating olive oil over low-medium heat. SLOWLY add in the flour and whisk together until combined.
3 tablespoon extra virgin olive oil, 3 tablespoon all-purpose flour
Turn up stove to medium heat. SLOWLY add milk and whisk. In 1-2 minutes the mixture will start to thicken QUICKLY. Continue whisking until it forms a dough ball. Once the dough has formed immediately remove from heat so it doesn't burn.
½ cup unsweetened non-dairy milk
Begin to cook pasta to package instructions until al dente.
8 oz macaroni noodles
Once veggies are fork-tender drain them but SAVE THE LIQUID in a bowl.
In a food processor or high speed blender, add in veggies, flour mixture, spices, dijon mustard, lemon juice, nutritional yeast and ¼ cup veggie liquid. Blend on high for 1-2 minutes until smooth. If your sauce is too thick add 1-2 tablespoon of veggie liquid at a time until it's at the desired consistency.
½ teaspoon garlic powder, 1 teaspoon salt, 2 tablespoon nutritional yeast, ½ teaspoon dijon mustard, 1 tablespoon lemon juice, ½ teaspoon turmeric, Pinch pepper
Pour sauce over cooked noodles. Gently mix and enjoy!
