Instant Spinach

1 pound spinach leaves (e.g., Savoy, tough stems removed)
2 TBS olive oil
2 tsp fresh lemon juice
1 tsp kosher salt
freshly ground black pepper

Pile the spinach in a large bowl that will fit in the microwave oven. Cook it on HIGH for 25 seconds, until it is warm but not wilted.  Toss the spinach with the oil, lemon juice, salt and pepper to taste.  Cook for 30-60 seconds until the spinach is wilted and its volume reduced less than half.  It should be hot, but not so cooked that it starts to throw off liquid.
