Give your gut some prebiotic love with Asparagus!

Spring is asparagus season and asparagus is one source of prebiotic fiber. Prebiotics give food to the microbes in our gut which, in turn, gives us health benefits (gut health, heart health, brain health and more!).

Roasted Asparagus

Ingredients:

1 bunch asparagus
Olive oil to taste
Salt to taste
A few cracks of black pepper

Directions:

Preheat the over to 400ºF.
Wash and trim the asparagus (I tend to break the woody ends off one at a time, feeling for where there is a natural break, but you can also just trim off the bottom inch or so with a knife).
Lay the asparagus out on a baking sheet and drizzle on the olive oil, followed by salt and pepper.
Mix the asparagus around so they all get coated with the oil and seasonings, then lay them out so there is no overlap.
Roast in the oven for 8-10 minutes.
