A recipe sentence. ごま油 ('sesame oil'), にんにく ('garlic'), 鶏肉 ('chicken'), 中華スープ ('Chinese soup stock'), 白菜 ('napa cabbage') are food vocabulary. 中火で ('over medium heat') is essential cooking terminology. The て-form chaining (熱し→入れて→炒め→入れて→煮る) sequences the steps. Dictionary-form 煮る at the end is the recipe imperative — instructions conventionally use plain form.
