Preheat the oven to 425° F. Line two, large baking sheets with parchment paper or *aluminum foil, set aside.
If making lentils from scratch, start them now. If using pre-steamed or canned lentils, wait until your vegetables are almost done roasting to reheat the lentils.
Add oil, sugar, cinnamon, salt, and cayenne to a large mixing bowl and whisk to combine. Add the cauliflower and squash, toss until well coated. Transfer the cauliflower and squash to a lined baking sheet. Add the onion slices and chard to the bowl and toss, I use my hands and rub the veggies along the sides of the bowl to collect all the remaining oil and spices. Add the onions and chard to the second baking sheet. Add the baking sheet with the cauliflower and squash to the oven and roast for 15 minutes.
While veggies start to roast, make sure to start your quinoa (instructions follow).
After 15 minutes, remove the baking sheet and flip the veggies. Return to oven for another 10 minutes, adding the second baking sheet, of onion and chard, in the last 7 minutes. The vegetables should all be roasted and *tender.
Heat a large skillet over medium heat, do not add any oil. Once hot, add the almond slices to the skillet and sprinkle with salt. Keep the almond slices constantly moving in the skillet until toasty and browned. They should have a nice aroma.
