Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Cut the top off each tomato and scoop out the seeds and pulp, leaving a 1/2-inch shell. Place shells cut-side up on a parchment-lined baking sheet.
  2. Step 2: Mash 1 avocado with 1/4 cup diced tomato pulp, 1 tbsp lemon juice, 1 tbsp dill, 1 tbsp olive oil, 1/8 tsp salt, and 1/8 tsp pepper until smooth.
  3. Step 3: Divide avocado mixture evenly among tomato shells, pressing gently to fill. Top each with a handful of fresh spinach and a thin slice of lemon.
  4. Step 4: Bake for 15 minutes until tomatoes are tender but hold their shape. Serve immediately.
