Step 1

Preheat oven to 325°. Toss garlic, thyme, orange zest, ginger, tomatoes, orange juice, oil, brown sugar, salt, and a pinch of pepper in a 13x9” baking dish. Roast, gently tossing mixture every 20 minutes, until tomatoes are tender and just bursting but still intact, 50–60 minutes. Pluck out and discard thyme and orange zest.

Step 2

Separate spring onion stems from bulbs. Cut stems in half lengthwise, then cut crosswise into 2” pieces. Slice bulbs through root end into quarters. Heat a dry medium skillet, preferably cast iron, over high. Add 1 Tbsp. oil, then sugar snap peas, and shake pan so sugar snaps spread out in a single layer. Cook, tossing once, until charred on both sides, about 4 minutes. Transfer to a large bowl.

Step 3

Heat remaining 1 Tbsp. oil in same skillet. Add spring onion stems and bulbs, arranging in a single layer. Cook, tossing once, until charred, about 4 minutes. Transfer to bowl with sugar snap peas; season with salt.

Step 4

Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain, transfer to a large bowl, and let cool, tossing around now and again to make sure it’s not sticking.

Step 5

Add tomato mixture, sugar snap peas and spring onions, lemon juice, 1½ cups basil, and 1½ cups mint to pasta and toss gently to combine (you don’t want to break up the tomatoes too much); season with salt, pepper, and more lemon juice if desired.

Step 6

Serve pasta salad topped with remaining ½ cup basil and ½ cup mint and a drizzle of oil.
