1 bag 15 bean soup mix (seasoning packet removed)
 2cups brown rice
Mix and add to a large pot of cold water. Bring to a boil and simmer 30 minutes. Rinse with cold water.
Add I lg bag frozen corn
1 lg bag frozen mixed vegetables
1 small bag frozen chopped broccoli - larger and they won't eat it.
1/2 cup each shelled sunflower seeds and brown sesame seeds.
I chop 2 sweet potatoes, or other vitamin A rich vegetable (carrot, squashes) finely in the food processor, and microwave in a large bowl for 10 minutes to blanch, and stir this into my bean mix before adding the frozen vegetables.

This food can spoil if left too long in the cage. If you work a long day, you can feed it for breakfast and remove it, and feed it again at dinner. Do not leave it longer than 4 hours in the cage, especially in Summer, as it will get rancid. Older birds do fine with fruits and vegetables and a dry food (no pellets!) like Goldenfeast Madagascar Delight if they must be left for a long time, but the bean mix is important for newly weaned babies, whose tastes run towards warm, mushy foods. Older birds should have it at least once a day. I feed it twice 

Preheat oven to 375 degrees. 
Add 1T of baking powder and 2c corn meal to food processor and blend
Throw in 2 eggs, shell and all
From here you can get creative: greens, sweet potato, canned or fresh pumpkin, etc. The idea is to make a moist batter you can bake.
Oil a black iron skillet or other teflon-free baking dish and add the batter. Bake 30 40 min or until a toothpick inserted in the center comes out clean. Cool and cut into sections and freeze what you don't intend to use right away.
