Any experience growing grains in your family garden???

We are wanting to get some more gardening beds in... we are so new at this it is pathetic... anybody have any experience growing grains in their family garden? I hear quinoa is a perfect protein??

Maybe I should just start working the lasagna bed layers and get it ready for winter wheat?? (I like the lasagna idea to hold in moisture and help prevent the weeds... and if I get the used stable straw and manure... I should be able to avoid fertilizers??)

Anybody know how long it takes for horse manure to be ready to plant?? (so it doesn't burn the plants??)

Sorry for all the questions! Thanks in advance for any help!!!!
