Step 1

Using a spiral vegetable slicer, cut zucchini lengthwise into long, thin strands. Give the strands a chop here and there so the noodles aren't too long. Place the zucchini in a colander and toss with 1/4 teaspoon salt. Let drain for 15 to 30 minutes, then gently squeeze to remove any excess liquid.

Step 2

Meanwhile, place basil, pine nuts, Parmesan, 1/4 cup oil, lemon juice, garlic, pepper and 1/4 teaspoon salt in a mini food processor. Process until almost smooth.

Step 3

Heat 1 tablespoon oil in a large skillet over medium-high heat. Add chicken in one layer; sprinkle with the remaining 1/4 teaspoon salt. Cook, stirring, until just cooked through, about 5 minutes. Transfer to a large bowl and stir in 3 tablespoons of the pesto.

Step 4

Add the remaining 1 tablespoon oil to the pan. Add the drained zucchini noodles and toss gently until hot, 2 to 3 minutes. Transfer to the bowl with the chicken. Add the remaining pesto and toss gently to coat.
