Chop the Veggies: Chop the tomatoes into large chunks. Cut the avocado in half and carefully remove the pit. Cut into large chunks and use a spoon to scoop it out. Thinly slice the red onion.
Make the Dressing: In a small bowl, combine the fresh lemon juice with the balsamic vinegar. This tangy dressing will tie everything together.
Assemble the Salad: In a medium mixing bowl, gently toss together the chopped tomatoes, diced avocados, and red onions. Pour the dressing over the top and give everything a light mix, ensuring the flavors coat all the ingredients. If using, sprinkle some Everything Bagel Seasoning on top for extra flavor. Salt and pepper to taste and enjoy!
Notes
Leftovers: This salad is best served fresh. If you have leftovers, store them in an airtight container in the fridge for up to a day. Keep in mind that the avocado may begin to brown after a day.
