Design a fun and playful food photography scene showcasing gourmet tacos filled with grilled vegetables and topped with a drizzle of creamy sauce. The tacos should be artfully arranged on a bright kitchen counter, with fresh ingredients like diced tomatoes and lime halves scattered around. Capture the image in bright, natural light to enhance the colors and textures, using a wide aperture for a shallow depth of field that draws attention to the tacos. The overall composition should evoke a sense of freshness and excitement, inviting viewers to indulge in the culinary delight.
