Vegan White Bean Nacho Cheese Sauce

1 15 ounce can of white beans (I used cannellini beans), drained and rinsed
2 cups vegetable broth
1 large jalapeno, roughly chopped
1 teaspoon of garlic powder
1 teaspoon of cumin
1/3 cup of nutritional yeast
2 tablespoons of dijon mustard
2 heaping tablespoons unbleached flour
1/2 cup of red bell pepper, chopped

In a medium pot, stir together the beans, broth, jalapeno, and spices. Bring to a boil.
Reduce heat to a simmer. Stir in the nutritional yeast, dijon. Whisk in the flour and continue to whisk until the sauce begins to thicken. Remove from heat.
Add in the bell pepper.
Blend the mixture using an immersion blender
