Tortilla Primavera

• Spring Pesto (Makes about 16 ounces, or 2 cups)
• 1 bunch asparagus
• 1 bunch spinach
• 1/4 cup chopped chives
• 1/2 cup pine nuts
• 1 cup finely grated Grana Padano cheese
• freshly grated black pepper
• 1/2 teaspoon kosher salt
• the juice and zest of a small lemon
• 1/3 cup olive oil
• Tortilla
• 1 medium yellow onion
• 2 medium Yukon Gold potatoes
• 1/4 cup good olive oil
• 6 eggs
• 1/4 teaspoon freshly ground black pepper
• 1/2 tablespoon kosher salt
• 1 tablespoon olive oil
• 1/4 cup of minced chives
• Maldon sea salt

1. Wash the asparagus, and then peel or cut off the tough bottoms; discard. Blanche the asparagus in simmering water for 2 minutes, just until they turn bright green and become a little tender. Immediately move them to an ice bath, to arrest cooking. Dry the asparagus, chop it up, and move it to the bowl of a food processor. Similarly, wash the spinach, and then blanche that too (you can use the same water). Try to squeeze as much moisture out of the spinach as possible. Move the drained spinach to the food processor, also. Chop the chives, and add them to the food processor as well.
2. Add the pine nuts, the cheese, the black pepper, the salt, and the lemon juice and zest to the food processor. Turn on the machine, and pour in the olive oil in one steady stream. When the pesto is blended to a fairly smooth consistency, give it a taste; adjust the seasoning as necessary.
3. Halve, and then thinly slice, the onion. Peel the potatoes. Slice them in half, lengthwise, and then cut all four halves crosswise, quite thinly. (You want thick-ish, half moon potato chips.)
4. Pour the olive oil into an 8-inch pan; warm the oil over low heat. Add the onion, and saute for 1-2 minutes. Add the potato, and stir gently to coat with the olive oil. Cook for about 15-20 minutes, until the potatoes are soft but not browned. (Since I cut the potatoes quite thinly, some pieces fell apart as I stirred occasionally; it's not the end of the world.)
5. Crack the eggs into a large bowl, and scramble them with a fork or whisk. Add the salt and pepper, along with the cooked potatoes and onion. Tent the bowl with plastic wrap, and let it sit for a while; the warm potatoes will release starch into the egg mix, everything will marry together, and the resulting omelette texture will be soft and lovely. (I left the bowl on the countertop for 1 hour, but any longer than that, move the bowl to the fridge.)
6. ---------------------------------------
7. In the same pan you used to cook the potatoes, heat 1 more tablespoon of olive oil over low heat. Stir another 1/4 cup of minced chives into the reserved egg mixture, and then pour that into the pan. Use a spatula to swirl in 1/4-1/2 cup of the pesto. Cook the omelette on medium-low heat for about 20 minutes, or until the oil is bubbling gently around the edges of the pan, and the egg looks almost set.
8. Now comes the tricky part: you need to flip the tortilla. Turn off the range, and put on some oven mitts. Lay a large plate (it has to be larger than the pan) face down across the pan. Carefully, flip the pan upside down, so that the omelette falls onto the plate. Place the pan back onto the range, and turn the heat back on. Using a spatula to aid you, slide the omelette back into the pan. Cook the tortilla for another 5-7 minutes. Finish with a sprinkle of Maldon sea salt.
