Show only first level courses in recipe-course page

Hi,

I have set up my courses as a 2 level hierarchy and I use it to sort my recipes. I have 5 main courses (Breakfast, Entree, Lunch, Dessert, Drinks) and at least 20 sub courses. I have ordered my courses in the order I want them to appear.

Is there a way to show only the main courses on the recipe-courses page and also keep the taxonomy order I defined?

The same exists for the other taxonomies (recipe-cuisines, recipe-keys, recipe-tag, etc…)

Thanks
