Preheat the oven to 375 degrees and line a baking sheet with parchment paper. Combine all of the tempeh bacon marinade ingredients in a bowl. Dip each piece of tempeh in the marinade, letting the excess drip off, and place on the baking sheet. Set aside.
Combine all of the crouton ingredients in a bowl and toss to combine. Transfer to a separate baking sheet. Place the tempeh bacon and the croutons in the oven and bake for 20 minutes, flipping both halfway. Remove from the oven and set aside.
Increase the oven heat to 425 degrees and add a fresh piece of parchment paper to the baking sheet you cooked the tempeh bacon on. Slice the sweet potatoes and place in a bowl with the olive oil, garlic powder, smoked paprika, pepper and salt. Toss until fully coated. Place the sweet potato on the baking sheet and bake for 40 minutes, flipping halfway.
Meanwhile, prepare the caesar dressing by adding all of the ingredients to a food processor and pulsing until combined. Taste and add salt if needed. Set aside.
Cut the cooled tempeh bacon into bite-sized pieces.
To assemble, add the brussels sprouts, kale, tempeh bacon, croutons and half of the dressing to a large bowl. Toss to combine. Top with the sweet potatoes and avocado. Serve with the remaining dressing on the side.
Notes
*You can buy brussels sprouts pre-shredded. I still like to give them a rough chop to break up any of the bigger pieces.
