Olive Oil

One of the healthiest oils around,olive oilis one I use every day.

I use it for meal-preppingfrittatasandsalad dressing, cooking quick dinners likeBurrata Pasta with Cherry Tomatoes & Spinachand more.

Since we go through so much of it, I typically buy it from Costco.

I also use it to fryfalafel, make stir-fries and more.

So I keep a large container of ranch dip and dressing mix around.

Oats

This high-fiber whole grain is a staple in our house.

My husband eats oats every other morning, and I make muesli in bulk throughout the year.

We also makehomemade energy ballsthat our daughter takes to school.

I also crack open a box of stock to make tasty pan sauces, deglaze pans and more.

Buying it in bulk ensures I don’t run out.

Almond Milk

My husband would really love to be vegan but hasn’t managed to make the switch completely.
