Preheat Oven to 425°F If you have a convection oven, use it! Line a baking sheet (or two) with tinfoil, parchment paper or a silicone mat. I use a rather large sheet pan which is the equivalent size of two standard-sized ones.
Sweet Potatoes
Peel and Cut the potatoes into 1.5" cubes. Place them onto the sheet pan and then toss them in the oil, sugar, salt and pepper.
Chicken
In a large bag (such as Ziplock) add oil, salt, pepper, paprika, thyme, oregano, parsley and diced garlic cloves. Add in chicken and toss until evenly coated.
Nestle the chicken on the sheet pan with the sweet potatoes.
Bake for 15 Minutes
Cauliflower
While the Chicken and Sweet Potatoes are baking; Break down the cauliflower into smaller pieces. (2"-3" in size)
Add the Cauliflower into the bad you tossed your chicken in. Then add in your Red Pepper Flakes, Garlic Cloves, Salt and Pepper. Shake until they are evenly coated.
Once the timer has gone off, add the cauliflower to the sheet pan with the chicken and sweet potatoes.
Bake for 15 Minutes
Asparagus
While the cauliflower Bakes; Wash and trim the asparagus. Place it in your bag and add the juice of half a lemon along with salt and pepper.
Once the timer has gone off, add the asparagus evenly on top of the sheet pan and bake for 10 minutes.
