Toast the baguette slices in the oven for about 10 minutes at 375° F(190°C), or in the air fryer for 3 minutes. Drizzle 1 tablespoon of olive oil over the crostini.
Place the chickpeas in a bowl and cover with hot water. Add baking soda and stir.
Microwave for 90 seconds. Run water into the bowl while massaging the chickpeas. This will take the skins off the chickpeas.
Add the still warm chickpeas, 2 tablespoons of olive oil, tahini, garlic, and lemon juice in a mini chopper or food processor. Blend until smooth. If necessary to get it smooth, add 1 teaspoon of warm water. Continue to blend until really smooth.
Toast the pine nuts in a pan over medium heat until lightly golden brown.
Top each crostini with hummus, olive mixture, and pine nuts. Drizzle the remaining olive oil over the top and sprinkle with paprika.
