This spring vegetable tart looks like a work of art, but it's so easy to accomplish. Puff pastry isn’t the healthiest item in the world, but for special occasions, it transforms simple ingredients into something fun and festive.
Thaw the puff pastry sheets for 45 minutes to an hour before using. Carefully unfold and arrange on two parchment-lined baking sheets.
Preheat the oven to 400º F.
Heat the oil in a large skillet or stir-fry pan. Add the onion and sauté over medium heat. until translucent. Add the garlic and continue to sauté until the onion is golden.
Add the bell pepper, asparagus, and mushrooms to the skillet. Cover and cook for 2 to 3 minutes, lifting the lid to stir occasionally, just until the asparagus turns tender-crisp.
Add the spinach and dried tomatoes. Cover and cook just until the spinach wilts down, 1 minute or less. Remove from the heat and season to taste with the seasoning blend, salt, and pepper.
Grate the cheese and sprinkle evenly over the surface of the puff pastry. Distribute the vegetable mixture evenly over the surface of the pastry, then create a little lip by folding all four edges over just about a half inch.
Bake for 15 minutes, or until puffed and golden. Allow to stand for 5 minutes. Cut each into 6 sections, then serve.
