Toast and season bread: Toast bread in a toaster or toaster oven until crispy, then remove to a plate. Drizzle each piece of bread with 1 teaspoon olive oil (save remaining olive oil for arugula). Then sprinkle the bread with garlic powder and onion powder.
Season and toss arugula: Place arugula in a small bowl and add remaining olive oil, lemon juice, and a pinch of salt and pepper. Toss to completely coat arugula leaves.
2 tablespoons olive oil, 1 cup arugula, 1 tablespoon lemon juice, 1 pinch salt and pepper
Build toast: Place sliced avocado on top of the toasted and seasoned bread. Top with arugula salad, then garnish with red pepper flakes and your choice of seeds (if desired). Then enjoy!
Prep ahead: This recipe is best made right before eating, but if you’d like to reduce prep time simply make the arugula salad up to two hours ahead of time (making it too far in advance will mean wilted arugula).
Leftovers and storage: Store leftover toast in an airtight container in on the countertop or in the refrigerator for up to one day.
Nutrition notes: This recipe uses only plant-based ingredients, which makes it suitable for vegan diets. Use gluten free bread for a gluten free option. Nutrition information is an estimate and does not include optional seed garnishes.
