Alternative Ingredient Suggestions
If you’re missing an ingredient or need to make a quick substitution, here are a few ideas:
- Tropical Twist: Swap out watermelon for cantaloupe or honeydew for a melon medley that’s just as refreshing.
- Spicy Kick: Add diced jalapeños for a little extra heat and depth to the flavor.

Step-by-Step Instructions for Mexican Watermelon Cucumber Salad
- Prepare the Watermelon: Dice the watermelon into bite-sized pieces. Place the diced watermelon in a colander to allow any excess water to drain out. This prevents the salad from becoming soggy.
- Toast the Pepitas: In a dry pan, toast the pepitas over medium heat for about 5 minutes, tossing frequently to avoid burning. Once golden, set them aside to cool.
- Chop the Vegetables: Slice the cucumber into thin rounds and dice the red onion. Set them aside along with the fresh herbs.
- Make the Dressing: In a small bowl, whisk together olive oil, lime juice, red wine vinegar, and Tajín seasoning until well combined.
- Assemble the Salad: In a large bowl, combine the drained watermelon, sliced cucumber, toasted pepitas, and red onion. Pour the dressing over the mixture and toss gently with a slotted spoon to combine all the ingredients evenly.
- Add Fresh Herbs and Serve: Sprinkle fresh herbs over the top and give the salad one final toss. Serve immediately for the best flavor and texture.
