Steps
1. Preheat your oven to 400°F (200°C).
2. Slice the whole grain bread into 1/2 inch thick pieces and place them on a baking sheet.
3. Drizzle the bread slices with olive oil and toast in the oven for about 5-7 minutes, or until golden brown.
4. While the bread is toasting, scoop the avocado into a bowl and mash it with a fork.
5. Add the diced tomato, chopped basil, lemon juice, salt, and pepper to the mashed avocado, stirring gently to combine.
6. Once the bread is toasted, remove it from the oven and let it cool slightly.
7. Top each slice of toasted bread with the avocado mixture.
8. Serve immediately as a fresh and vibrant appetizer.
