Preparation

• In a large bowl, whisk 1/4 cup of the oil with the lemon juice, maple syrup, 1 1/2 tsp. salt, and 1/2 tsp. pepper. Set aside.
• In a 3-quart pot, bring 1½ cups water to a boil. Cook the couscous in the boiling water according to package directions until the water is absorbed. Toss with the vinaigrette.
• In a 10-inch skillet, heat the remaining 1Tbs. oil over medium-high heat. Add the scallions and cook, stirring often, until browned in spots, 2 to 3 minutes. Add the garlic and cook, stirring, until fragrant, 5 to 10 seconds. Combine with the couscous, and thentoss with the chopped mint and parsley.
• Core the tomatoes, slice a tiny bit off their bottoms to create a level base, cut off their top 1/4 inch, and then seed them with a spoon. Drain the flesh and seeds in a colander, then chop and add to the couscous. Season to taste with salt and pepper. Divide the mixture among the tomatoes, garnish with the mint leaves, and serve.
