Instructions
Place potatoes in a pot and submerge in salted water. Cover and bring to a boil. Once boiling, lower heat to simmer and cook for about 15 minutes, or until potatoes are tender.
Drain potatoes and immediately transfer them back into the pot. It’s important to do this while everything is still hot. Give them a quick preliminary mash, then add the milk, olive oil, lime zest and salt. Mash until creamy, taste for salt, then cover and set aside. (Note: I usually add black pepper, but decided not to here so that the lime really shines through. If you feel naked without it, though, go ahead and add some.)
To prepare the stew:
Preheat a large, heavy bottomed pan over medium-high heat. Saute onion and pepper in olive oil and a pinch of salt, until peppers are softened, about 10 minutes. In the meantime prep all your other ingredients.
Add garlic and saute until fragrant, 30 seconds or so. Add mushrooms and cilantro and cook until the mushrooms have released a lot of moisture, about 5 minutes. Add tomatoes, corn, wine, salt, cumin and red pepper flakes. Turn heat up and cover the pan, stirring occasionally, for 5 to 7 minutes. The tomatoes should break down and become saucy (if corn was frozen it may take a bit longer.)
Now take the tortilla chips and crush them into fine crumbs with your hands. It’s ok if there are a few bigger pieces, but aim for crumbs. Add them to the stew and mix well. Since tortillas can be salty, wait until they’re added to taste for salt. Mix in the lime juice and hot sauce, then fold in the black beans and heat through. Now taste for salt and seasonings.
To assemble:
Preheat oven to 350 F. Lightly grease a deep 11×13 casserole (cooking spray works just fine). Transfer the stew to the casserole and even it out with a spatula. Add the potatoes in dollops, and spread it into an even layer.
Place in oven and bake for about 25 minutes, until potatoes are lightly browned. Stick under the broiler for a minute or two just in case the browning isn’t happening. Serve hot garnished with cilantro, chili peppers and lime.
