Some more things that could help.
Try having a bowl of oats for breakfast. These are low GI, and cheep they will keep you full for longer and they contain less calories then toast. You can even add a spoon of brown sugar or some dried fruit while cooking and serve with milk. YUMM.
For snacks try making your own muesli bars and biscuits. They are a lot healthier then store bought and taste 10 times better. So for morning tea, have a piece of cheep fruit and a muesli bar.
For lunch on your salads, i would not use croutons, they are just bread soaked in fat and roasted. instead look into some short grain brown rice or quinea to use. I would also look at tinned legumes like kidney, chickpea or cannelloni to add protein and fibre, both which will keep you fuller for longer.
Try to drink a minimum of 8 cups of water a day. A good change from kool-aid (i had to look up what this was) is a squeeze of orange or lemon concentrate (you can get this in the sauce isle of your supermarket).
My general philosphophy is if i can't tell what it looked like coming off the plant, i won't eat it.
A good easy muesli bar recipe is 1/2 cup honey, 1/2 cup butter or marg. Melt together in a pot until a light brown colour. Then mix with 1 cup oats, 1/2 cup diced mixed dried fruit of choice, 1/2 cup seeds (eg pumpkin, sunflower ect). combine and put in a lined slice tin and bake on 150 degrees for 35minutes. cool in tin and then slice and wrap individually.
