  • ¾ cup uncooked quinoa
  • 1 ½ cups water
  • ¼ tsp salt


  • 6 cups sweet potatoes cubed (about 2 medium)
  • 1 red pepper cut into 1” square pieces
  • 1 green pepper cut into 1” square pieces
  • 1 cup shelled edamame
  • 3 TBS olive oil divided
  • 1 ¼ tsp garlic salt divided
  • ¼ tsp pepper

Honey Mustard Sauce:


  • Cook quinoa according to package instructions. Set aside.
  • Preheat oven to 425 degrees F. Lightly grease a large baking sheet, set aside.
  • Dice sweet potatoes and place in a microwave safe dish. Microwave for 6 minutes. (If you don’t want to use a microwave, skip this step and proceed to step 2)
  • Toss diced sweet potatoes with 2 TBS olive oil until coated.
  • Sprinkle 1 tsp garlic salt on potatoes and mix until evenly distributed.
  • Spread sweet potatoes evenly on a baking sheet and bake in preheated oven for 15 minutes or until slightly browned (if you don’t want to use a microwave, bake 15 minutes then stir and bake another 10 minutes before proceeding to the next step).
  • While sweet potatoes are baking, toss green peppers and shelled edamame with remaining 1 TBS olive oil and ¼ tsp garlic salt.
  • After sweet potatoes are slightly browned on one side, add the peppers and edamame and stir until everything is evenly distributed on your baking sheet.
  • Bake for an additional 20 minutes, stirring every 10 minutes until the peppers are cooked and everything is slightly browned.
  • Make the honey mustard sauce: While the veggies are roasting, stir together all honey mustard sauce ingredients until combined.
  • Add 2 TBS of the sauce to the already cooked quinoa, set aside.
  • Once the veggies are all slightly browned (after about 30-35 minutes total of roasting time), add the rest of the honey mustard sauce to the vegetables and stir until evenly coated.
  • Bake for 10 additional minutes, stirring once halfway through, until the sauce has thickened and has coated the vegetables.
  • Remove the pan from the oven and add the quinoa to the vegetables and stir until combined.
  • Serve warm or wait until the salad has cooled to room temperature, store in an airtight container in the refrigerator and serve cold!
