Preheat your oven to 400F/200C and line a baking sheet with baking paper. Cut the broccoli into bite-sized florets and transfer them to a bowl. Add 2 tbsp of olive oil and ¼ tsp of salt and toss to season.
Peel, deseed, and cut the acorn squash into bite-sized cubes. Transfer them to a bowl and add 2 tbsp olive oil, maple-flavored syrup, cinnamon, and ¼ tsp salt. Toss well.
Transfer the broccoli to one side of the baking sheet and the acorn squash to the other. Spread them, but keep a gap between the vegetables—Bake for 15 minutes.
Take the baking sheet out of the oven and turn the vegetable to ensure even browning. Bake for another 10-15 minutes, or until slightly charred around the edges. Set the baking sheet aside.
Finely chop the bacon and transfer it to a pan. Cook over medium heat until crispy. Discard the grease and set it aside.
To assemble, combine the roasted veggies, bacon, pumpkin seeds, sunflower seeds, and lemon juice in a bowl. Toss to combine. Taste and adjust the seasoning to your liking. You can serve it warm or cold.
