1. Preheat oven to 400°F (204°C).
2. Cut acorn squashes in half. Chop off stems or tails so that they can lay flat.
3. Leaving seeds inside, roast squash halves face down on a baking sheet for 50 minutes.
4. Flip squash over. Then, using a spoon, remove and set aside seeds.
5. While the squash is in the oven, in a separate pot, cook rice and lentils in vegetable broth. Drain and reserve liquid.
6. Cook the Brussels sprouts in the leftover vegetable broth for 8 minutes, then drain well and set aside.
7. In a large pan, cook onions and mushrooms on high until mushrooms release liquid.
8. Add garlic, herbs and spices (except fresh rosemary) and cook for 5 minutes.
9. Add lentils, rice, and Brussels sprouts. Add additional liquid (water or broth) if too dry.
10. Season with salt and pepper to taste.
11. Remove the mixture from the heat, stir in 1/2 cup of the cherry tomatoes then season with salt and pepper.
12. Fill squash halves with rice mixture.
13. Top with remaining ¼ cup halved cherry tomatoes, fresh rosemary and balsamic reduction.
