First things first: wash your tomatoes and avocado under cold water.
Dice those tomatoes. Use a sharp knife and aim for even cubes. Then toss ’em into a big bowl.
Halve the avocado, remove the pit, and then scoop out the good stuff. Dice it and add it to the tomatoes.
Now, toss in the chopped red onion.
Time for cilantro! Add it to the mix.
Let’s make that dressing. In a small bowl, whisk together olive oil, lemon juice, salt, pepper, and a teaspoon of crushed red pepper flakes.
Drizzle this yumminess over your tomato and avocado mixture.
Mix it up! But be gentle; you don’t want to mush it all together.
Taste-test time. Adjust salt and pepper if you need to.
