Prepare the ingredients as instructed above.
Make the pico de gallo: In a small bowl, combine tomato, red onion, jalapeño (if using), cilantro, lime juice, olive oil, and salt. Stir well and let sit to meld flavors.
Toast the bread.
Cook the eggs: Melt butter in a nonstick skillet over medium heat. Crack eggs in, season with salt and black pepper, and cook sunny-side up or to desired doneness, about 2–3 minutes.
Assemble the toast: Spread mashed avocado evenly over each toasted slice. Spoon pico de gallo on top.
Serve the avocado toast with eggs, fresh fruit and orange juice. Enjoy!
