Cooking extra food at the beginning of the week is the key to making my life way easier Monday through Thursday (Friday is takeout night!).

Cook Once, Eat All Week is here to help you prep the basics for healthy meals (lots of veggies, along with some grains and pulses) ahead of time, then give you the simple recipes to turn those ingredients into hearty, satisfying meals.

And this might be my simplest meal prep session yet. I decided to take a bunch of sweet potatoes, roast them up, and make them the base of my meals for the week. And by "bunch" I mean 8 small (or 4 to 5 large) sweet potatoes — enough to make 2 servings of each of the four dishes below.

Sure, that's a lot of sweet potato, but they're versatile, comforting, and oh-so-good for you.

Plus, you can most definitely freeze the soup and meatless Sweet Potato and White Bean Balls for a rainy day.

Sunday Prep

1. Roast sweet potatoes.

Heat oven to 425°F. Wrap each sweet potato in foil. Pop in the oven, and roast for 1 hour or until soft.

2. Roast cauliflower.

Chop cauliflower into florets on an oiled baking sheet with a sprinkling of salt for 30 minutes until golden.

3. Sauté greens.

Clean and chop Swiss chard into ribbons. Sauté with olive oil in a large pan with 1 garlic clove, finely chopped (or grated on a microplane) and a pinch of salt. Cook for 5 minutes and set aside.

3. Roll the sweet-potato-and-white-bean mash into golf ball–size balls (the mixture should make about 8 balls) and place on the oiled baking tray.

5. While that’s in the oven, toss tomatoes with a drizzle of olive oil and pop those in the 400°F oven too. Cook tomatoes for 15 to 20 minutes, until golden brown in spots and beginning to collapse.
