Making my own baby food?

My baby is 5 1/2 months old and for the most part can sit up by himself without support. My pediatrician told me i can start baby food but he doesnt seem to get full with step 1 baby food by gerber, since its nearly 90% water. so i want to start making my own baby. does anyone have or know of any recipes for this? he likes carrots, green beans,peas, sweet potatoes, all that stuff. i just started making him cream potatoes too using a real potatoe and his formula. im kinda nervous about not putting enough water or too much water. also what about fruits? hes loves fruit in his cereal or oatmeal. i have a little food chopper to puree his foods also if that helps
