Every party needs a delicious dip and this one is sure to be a favorite.
In a large skillet, add the tomatoes, peppers, onion, and garlic to the same pan and cook for 2 to 3 minutes until softened and fragrant. Whisk together the milk and starch in a small glass or bowl until completely smooth, then pour into pan and reduce heat to low. Add the spices, salt, and pepper and stir constantly until the sauce begins to thicken.
Add the lime juice, yogurt, cheese, and nutritional yeast and continue stirring over lowest heat until evenly melted and creamy. Season to taste with more salt and pepper to taste and if desired top with green onions.
