Pat the chicken breast dry and season with salt, pepper, and a touch of dried oregano.
Heat one teaspoon of olive oil in a grill pan over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken cooks, rinse and thoroughly dry the chickpeas with a paper towel.
In a small non-stick skillet, toss the chickpeas with a half teaspoon of olive oil and toast over medium heat for 5-8 minutes until they become golden and slightly crunchy.
In a medium bowl, whisk together the remaining olive oil, lemon juice, salt, and pepper to create the dressing.
Add the diced cucumber, halved cherry tomatoes, red onion, and toasted chickpeas to the bowl and toss well to coat.
Slice the grilled chicken into strips and serve immediately over the fresh chickpea salad.
