Whisk in the second tbsp of olive oil and flour until they are fully incorporated.
Slowly whisk in the rice milk, nutritional yeast, garlic powder, onion powder and salt until all ingredients are well combined. Bring to a boil.
Turn back down to low-medium heat and stir in the broccoli.
Let the mixture heat covered (lifting the lid and stirring occasionally) for about 5 minutes.
Uncover and cook for another 5 minutes.
Stir in the cooked pasta & serve in two bowls and enjoy (we love to top it with follow your heart vegan parmesan)! The sauce will thicken once cooled a bit.
