Preheat the oven to 400. Peel your sweet potato and cut into small cubes. Slice your onion in ½, then into 6 wedges, leaving the top intact so that the wedges will stay as one. On a baking sheet add you cut sweet potatoes and onion wedges and cherry tomatoes. Drizzle 2 TBSP olive oil over them and season with salt and pepper. Toss lightly to evenly coat them. Place in the preheated oven and roast for 10 minutes, then flip. Roast for another 10 minutes.
While your veggies are cooking, steam your edamame and then shell them. Set aside.
In a skillet, heat the last 2 TBSP olive oil and garlic and then cook chicken breast, seasoned with salt and pepper to taste.
In a small saucepan cook couscous according to the package directions.
To prepare the creamy sauce simply combine the yogurt, lemon juice, maple syrup, parsley and salt. When they are thoroughly combined, add a little water if it needs to be thinned out some.
When all of your ingredients are cooked you can now build your buddha bowl. One box makes 3 cups of couscous, I divide this among the 4 bowls and then lay one chicken breast in each bowl. Then I laid the onion wedge down and filled in the bowl, starting with ¼ cup of sweet potatoes, 4-6 cherry tomatoes along the side and then ¼ cup edamame filling in any open space. Then I added cashews along with my chicken. I then used a sandwich bag and put some sauce in it and cut the corner off, this helped me get a nice drizzle. You of course can just use your spoon too. Drizzles are just fun.
Enjoy!
