Prepare your ingredients: Start by draining the canned tuna and placing it in a mixing bowl. Slice your avocado and halve your boiled eggs, setting both aside.
Create a base: In a large bowl, add the fresh arugula or spinach. This leafy green goodness forms the perfect foundation for your bowl.
Combine the star ingredients: Place the drained tuna on top of your greens, followed by the sliced avocado and halved boiled eggs.
Add colors: Sprinkle the halved cherry tomatoes over the top, creating a vibrant display of fresh ingredients.
Season it up: Sprinkle salt and pepper to taste, and if you like, drizzle some olive oil or your favorite dressing over the entire bowl for an extra burst of flavor.
Serve and enjoy: Toss everything gently, if desired, and dig in with your fork!
