Prepare the Orzo: Prepare the orzo according to the package directions. Set the cooked orzo aside until ready to assemble the bowls. Heat the Skillet: Pour the extra virgin olive oil into a large skillet or non-stick pan and heat over medium heat.
Season the Chicken: Place the chicken breasts in the heated pan. Sprinkle half of the oregano, basil, salt, and pepper over the chicken. Cook the First Side: Cook the chicken for about 6 to 8 minutes, allowing it to become golden brown.
Cook the Second Side: Flip the chicken and sprinkle the remaining oregano, basil, salt, and pepper over the top. Cook for another 6 to 8 minutes, or until the juices run clear and the chicken is golden brown. Rest the Chicken: Remove the cooked chicken from the pan and let it rest for 5 minutes.
Slice the Chicken: After resting, slice the chicken thinly for easy assembly in the bowls.
Prepare the Vegetables: Cut the cucumber into slices and quarters, dice the shallots, and halve or dice the cherry tomatoes.
Dress the Vegetables: Add the prepared cucumber, shallots, and tomatoes to a bowl. Drizzle with lemon juice and season with additional salt and pepper if desired. Build the Bowls: Divide the prepared orzo among the serving bowls, placing it on the bottom of each bowl. Add the sliced chicken and vegetable mixture.
Add the Tzatziki: Spoon dollops of tzatziki sauce around each bowl so the creamy sauce is distributed throughout the ingredients.
Finish with Feta: Sprinkle the crumbled feta cheese over the assembled bowls.
Garnish with Mint: Add fresh mint sprigs if desired.
Serve: Serve the Greek chicken orzo bowls immediately.
