CHILES RELLENOS

Steps:

• To make the filling, combine oil, onions, garlic, and rice in a medium saucepan over medium heat. Cook until onions are browned, 10 to 12 minutes. Mix in chili powder, and cook for 1 minute more.
• Meanwhile, bring stock and salt to a simmer over medium heat. Add stock to rice, cover, and reduce heat to medium low. Cook for 25 to 30 minutes. Stir in acorn squash; add diced tomato without stirring. Cover, and cook 8 to 10 minutes more. Remove from heat, and let stand to steam for 5 minutes.
• To make the chili sauce, heat oil in a medium saucepan over medium heat. Add onions and cook, stirring frequently, until browned, about 5 minutes. Add garlic, cumin, oregano, tomatoes, chili powder, salt, lime juice, and 1 cup water. Bring to a boil, and simmer for 5 to 8 minutes. Let cool slightly. Puree in a food processor or blender, and return to saucepan. If sauce is too thick, add a small amount of water.
• Roast peppers over a gas flame or under a broiler until blackened, being careful not to break off stems. Place in a paper bag to cool. When cool enough to handle, peel peppers. Make a slit in the side of each from top to bottom. Wearing a rubber glove, scrape out the seeds. Stuff peppers with rice mixture.
• Heat oven to 375 degrees. Place 1/4 cup chili sauce in the bottom of a 9-by-13-inch glass baking dish, and arrange stuffed peppers, cut sides up, on top. Cover with foil, and bake for 10 minutes. Garnish with cilantro, and serve with warm chili sauce.
