Mix the diced tomatoes with the lemon juice, and then dice and add the avocado and remaining ingredients. Stir well. You can allow the flavors to mingle for a while in the fridge, or if you’re impatient like me, you can dig in right away.
Notes
About the chipotles: I used the chipotles that are canned in adobo sauce. They’re found in the Mexican or international sections of many grocery stores. If you can’t find them, you can substitute chipotle chili powder or any other chili powder. Chipotles are smoked jalapeños, and they give a smoky spiciness to this dish. Be aware, though, that they are very spicy, so use the “add a little, taste, add more” method if you’re sensitive to heat.
