Heat olive oil in a skillet over medium-high heat.
Season your chicken with salt, pepper, and chili powder.
Cook the chicken in the skillet, flipping periodically, until both sides are golden and chicken is cooked through (about 10-12 minutes).
Set the chicken aside and let it cool slightly.
Meanwhile, chop all your vegetables and fruits—lettuce, grapes, and blueberries.
Once the chicken is cool enough to handle, cut it into bite-sized pieces.
Assemble the salad: Combine the lettuce, chicken, grapes, blueberries, feta, and almonds in a large bowl.
Chill in the refrigerator while you make the dressing.
To prepare the dressing, blend almond butter, olive oil, orange juice, water, mustard, honey, salt, and garlic in a food processor until smooth.
Taste the dressing and adjust with more salt or honey if needed.
Drizzle the dressing over the salad, toss gently, and serve immediately.
