Turn your oven to 375 degrees and grease a baking dish with cooking spray or oil.
02 -
Toss the sliced sweet potatoes, diced squash, and sliced carrots with 1 tablespoon of olive oil, salt, and pepper. Spread them on a baking sheet and roast for 15 to 20 minutes until they're just tender. You want them cooked but not mushy since they'll bake more later.
03 -
Arrange a layer of sweet potatoes on the bottom of your greased baking dish. Sprinkle some crumbled feta and chopped walnuts over top.
04 -
Add a layer of butternut squash, then a layer of carrots. Keep layering the vegetables with feta and walnuts sprinkled between each layer until you've used everything up. Finish with a top layer of sweet potatoes.

In a small saucepan, combine the cranberry juice, honey, and balsamic vinegar. Bring it to a simmer and cook for 5 to 7 minutes, stirring occasionally, until it reduces down to a thick, syrupy glaze.
06 -
Drizzle about two-thirds of the cranberry glaze over the layered vegetables. Cover the dish tightly with aluminum foil and bake for 30 minutes.
07 -
Take off the foil and drizzle the remaining glaze over the top. Bake uncovered for another 10 to 15 minutes until everything is golden on top and bubbling around the edges.

Let the lasagna rest for about 10 minutes before slicing. This helps it set up so it doesn't fall apart when you cut into it. Serve warm.
