Beans and lentils are high protein, too. You need to offer cooked whole grains like oats, wheat, brown, black or red rice, kamut, barley and mix them with some thoroughly cooked (at high temperature) beans and/or lentils and the same amount (so the final mixture is half vegetables and half grains/beans) accompanied by one raw vegetable, one fruit and one leafy green (meaning something like lettuce, chicory, escarole, broccoli but no spinach, no collard greens). Then, in the evening, when the sun is halfway down to the horizon, you turn off the artificial lights and give them their seed/nut dinner (about 1/4 cup each).
Be careful about putting parrots out under the direct sun, it could get too hot for them and you can kill them of heatstroke (parrots are in trees, not out there under the sun for long periods of time).
