I am lucky in a thousand ways but got even luckier when the best Mexican in NYC opened practically right outside my door! Mexicana Mama serves roasted rellenos - I thought they all had to be battered, fattening and fried, no? NO! Sadly, the restaurant closes once a week for an entire day and night. So, on Mondays, I make this dish at home. It's so healthy, you might want to double the recipe because you can have guilt-free seconds!
Heat about 3 1/2 cups stock in a sauce pot with a bay leaf to boiling. Add rice, cover pot reduce heat to low and simmer 18 minutes until tender.
Place poblanos under broiler or on hot grill and char evenly all over, 15 minutes.
While peppers and rice are working, scrape the corn off the cobs or defrost frozen corn and dry by spreading out on clean kitchen towel. Heat 2 tablespoons light oil in a skillet over high heat. When the oil smokes or ripples add corn, onion, jalapenos and toss until the vegetables char at edges and onions are tender, 4 to 5 minutes. Reduce heat to medium-high and add in garlic, fire roasted tomatoes and season with cumin, oregano, salt and pepper. Cook another minute or 2 then turn pan off.
Place the cilantro, spinach, scallions, lime zest, half a cup of stock and a tablespoon of oil in food processor and process into coarse green paste. Stir into your rice pot in the last 3 to 4 minutes of its cooking time.
Sprinkle the lime juice over the corn mixture.
Split the charred peppers open but not in half with small sharp knife then scoop out the seeds with a small spoon. Place peppers in a shallow flameproof baking dish and stuff each split pepper with lots of the corn mix, top each pepper with 1/4 cup cheese and place back under broiler to melt and char the cheese.
