the oven to 400°F and line a with .
Preheat. Preheating means turning the oven on before you start, so it’s fully hot when the food goes in. Food that starts in a cold oven cooks unevenly and doesn’t brown the same.
How you’ll know: The oven beeps or its light clicks off, usually 10 to 15 minutes after you turn it on.
Sheet pan. A sheet pan is a flat metal baking tray with a low rim all the way around. The rim catches juices, and the wide surface lets food spread out and brown.
How you’ll know: Everything fits in one layer with a little space between the pieces.
Parchment paper. Parchment paper is a nonstick, oven-safe paper for lining pans. Food lifts right off and cleanup is easy, but don’t swap in wax paper or put parchment under the broiler.
How you’ll know: It lies flat in the pan, and the food slides off when you lift it.
Cut the squash in half from stem to tail and scoop out the seeds with a spoon.
Dolly’s tip: If it’s rock hard, stab it a few times and microwave it whole for 3 minutes. It cuts much more easily.Rub the cut sides with 2 teaspoons of the oil, the salt and the pepper, and lay the halves cut side down on the pan.

Roast. Roasting means cooking in a hot oven, around 400°F to 450°F, usually spread out on a sheet pan. The dry heat browns the outside and brings out sweetness, especially in vegetables.
How you’ll know: The edges are browned and a little crisp, and a fork slides easily into the thickest piece.

the tomatoes and chicken with the remaining oil, scatter them around the squash, and 12 to 15 minutes more, until the tomatoes burst and a fork slides easily into the squash.
Toss. Tossing means gently lifting and turning food so everything gets coated, like pasta in sauce or vegetables in oil. It coats every piece evenly without mashing anything.
How you’ll know: Every piece looks glossy or evenly coated, with no dry spots hiding underneath.

Food safety: Rotisserie chicken, deli meat, canned tuna and cooked shrimp are already cooked. Keep them cold until you use them, and heat them until steaming hot if the recipe warms them.
Let the squash cool 5 minutes, then scrape the flesh into long strands with a fork.

Dolly’s tip: Scrape across the squash, from side to side, and the strands come out long like noodles.the strands in a bowl with the pesto, chicken and tomatoes, and serve with the parmesan on top.
