Place the spinach into a large bowl. Add half of the feta, juice of ½ lemon, 1 tablespoon of olive oil and a big pinch of salt; rub the ingredients vigorously into the spinach to tenderize it. Leave to sit and soften further while you cook the gnocchi.

Heat a large (about 12-inch) cast-iron or nonstick skillet over medium-high; add 2 tablespoons of olive oil. Add the gnocchi to the pan, breaking up any that are stuck together. Cook for 8 to 10 minutes, tossing every 2 minutes, until golden and crispy all over. Allow to cool in the pan for 5 minutes; they will further crisp as they cool.

Add the gnocchi to the spinach, along with the red pepper, scallions, dill and mint. Drizzle with about 2 tablespoons of olive oil, add the remaining crumbled feta and toss to combine. Squeeze the remaining lemon juice over top and serve.
