If a fork still meets a hard center, cook for 3 more minutes and check again.叉子仍碰硬芯就再煮或烤3分钟重查。

Make it a balanced meal营养搭配建议
Balanced plate: ½ vegetables or salad, ¼ this dish, ¼ rice, bread or tortillas.均衡一盘：½蔬菜或沙拉、¼这道菜、¼米饭、面包或玉米饼。
Why it works: aim for half the plate vegetables, a quarter protein, a quarter whole grains or starch — then let one rich dish be the star.搭配思路：半盘蔬菜、四分之一蛋白、四分之一主食；一桌里只让一道浓郁的菜当主角。
