Fusilli with Yellow Squash & Grape Tomatoes

Put 2 quarts of water on to boil in a large pot.

Heat oil in a large skillet over medium-high heat. Add onion and cook, stirring frequently, until lightly brown, 4 to 8 minutes.

Meanwhile, if the yellow squash has a "crookneck," cut off the neck, halve it lengthwise and cut into 1/4-inch slices; quarter the wider part lengthwise and cut into 1/4-inch slices. If the squash is shaped like a zucchini, quarter it lengthwise and cut into 1/4-inch slices.

When the onion is lightly brown, add the squash, thyme, 1/2 teaspoon salt and pepper. Cook over medium-high heat, stirring frequently, until the squash releases most of its liquid and begins to brown, 7 to 10 minutes. Add tomatoes and cook, stirring occasionally, until they begin to break down, 4 to 6 minutes more.

Meanwhile, add the remaining 1 tablespoon salt to the boiling water, stir in pasta and cook according to package instructions until just tender. Drain well and toss with the sauce. Serve at once.
