Step 1Heat the oven to 375 degrees.
Step 2In a large bowl, gently toss the corn bread with 3 tablespoons pumpkin seed oil, the thyme, oregano, one-half teaspoon salt and several grinds of pepper. Spread the cubes in a single layer on a large, foil-lined baking sheet and toast for 20 to 25 minutes, until lightly golden, shaking the pan every 5 minutes for even coloring. Remove from heat and allow to cool, then place in a large bowl.
Step 3In a medium bowl, toss the pumpkin seeds with the remaining tablespoon pumpkin seed oil, one-fourth teaspoon salt and several grinds of pepper. Place the seeds on a foil-lined sheet and toast until fragrant, puffed and lightly golden, about 10 minutes. Remove and cool, then add to the corn bread.
Step 4Meanwhile, roast the chiles on the stove top directly over a hot burner until charred on all sides, about 5 minutes. Remove to a sealed paper bag to rest until cool enough to peel. Peel the charred skin (do not rinse under water as this will remove flavor). Halve the chiles lengthwise, stem and seed. Cut the halves crosswise into one-eighth inch strips, and add to the cornbread.
Step 5Heat a large heavy-bottom skillet over medium-high heat. Add 2 tablespoons butter and the olive oil, then the chorizo and cook until lightly browned, about 3 minutes. Remove the chorizo with a slotted spoon, leaving the fat in the pan, and add the chorizo to the stuffing mixture.
Step 6Stir the corn and onions into the pan and season with one-fourth teaspoon salt and several grinds of pepper. Cook, stirring occasionally, until the corn is crisp-tender and the onions have softened and are translucent, about 5 minutes. Stir in the garlic and cook until it is aromatic, about 30 seconds. Stir in the white wine and cook, scraping any bits of flavoring from the pan, until the white wine has almost evaporated, 2 to 3 minutes. Cool slightly, then add to the stuffing mixture.
Step 7Gently toss in the cumin and Spanish paprika, and season the stuffing with one-fourth teaspoon salt, or to taste. Melt the remaining butter and drizzle over the stuffing. Drizzle 2 cups chicken broth over the stuffing and gently toss. Add additional broth as desired.
Step 8Place the stuffing in a buttered, 13-by-9-inch baking dish or casserole and place in the oven. Cover and bake for 20 minutes, then remove the cover and continue to bake for 20 to 25 minutes, until the top is lightly toasted. Remove and serve.
