Combine all ingredients in a large bowl. Mix to combine. Serve.
If making ahead, cover with plastic wrap, pressing the wrap down onto the surface of the guacamole to prevent it from browning. Refrigerate until ready to serve.
Fajita Seasoning: We love fajita seasoning in guac, it gives it great flavor!! If you don't have any on hand, you can use garlic salt and freshly cracked pepper in its place. Storage: Refrigerate any leftovers in an airtight container for up to 3 days. Keep it away from heat and sunlight when on the counter or table for serving. Serve it straight out of the fridge or at room temperature. Unfortunately, this recipe doesn't freeze well.
