This is so simple. Peel and cut an acorn squash into section (any squash will do), peel and quarter 2-3 onions, seed and quarter 1-2 bell peppers. Liberally coat the vegetables with olive oil and sprinkle with coarse sea salt. Place on a cookie sheet and bake at 350F for approximately 40 minutes, turning the vegetables half way through.
I served the roasted vegies with salmon sauteed in olive oil, white wine, 1/2 cup vegetable broth, salt, olives and capers. Sorry I didn't follow through with this one as far as the steps.
