1/3 cup reduced-fat sour cream
1/2 cup chopped fresh chives, divided, plus more for garnish
3 tablespoons low-fat milk
2 teaspoons lemon juice
3/4 teaspoon salt, divided
1 tablespoon extra-virgin olive oil
2 cups chopped zucchini
1 1/4 cups chopped green beans
1 cup fresh corn kernels, (from 1 large ear; see Tip)
1 cup part-skim ricotta cheese
1/2 cup shredded Monterey Jack cheese
1/4 teaspoon freshly ground pepper
4 9-inch crepes
Stir sour cream, 1/4 cup chives, milk, lemon juice and 1/4 teaspoon salt in a small bowl until combined. Set aside.
Heat oil in a large nonstick skillet over medium-high heat. Add zucchini, green beans and corn and cook, stirring, until beginning to brown, 6 to 8 minutes. Reduce heat to low; stir in ricotta, Monterey Jack, the remaining 1/4 cup chives, the remaining 1/2 teaspoon salt and pepper. Cook, stirring gently, until the cheese is melted, 1 to 2 minutes. Remove from the heat.
To roll crepes, place one on a piece of parchment or wax paper (or leave it on the piece of plastic separating the crepes in the package). Spoon one-fourth of the vegetable-cheese mixture (about 3/4 cup) down the center of the crepe. Use the paper (or plastic) to help you gently roll the crepe around the filling. Place the crepe seam-side down on a dinner plate. Repeat with the remaining crepes and filling. Serve each crepe topped with 2 tablespoons of the reserved sauce and more chives, if desired.
