I need some meal ideas

Hard boiled eggs- cheap and simple. Add a slice of whole grain toast and you have a filling meal.

Oatmeal is cheap and filling!

Smoothies with frozen fruit, V8 or soy milk and either silken tofu or some sort of nut butter for some protein... watch the serving sizes with nut butter though because calories add up fast on this one.
Egg Beaters with some chopped up veggies. -- this is my favorite if I have the time.
Greek Yogurt with fresh fruit or honey (again watch the serving size).
This one is odd, but quinoa made the night before with some frozen fruit mixed in, in the morning is surprisingly delicious and filling.

I like to make a breakfast sandwich on an English muffin, with a scrambled egg or some egg whites (prepared in the microwave for convenience), a bit of ham/turkey/bacon/cheese or whatever, and a bit of spinach and tomato.

Dice an apple and top with 1/2 cup vanilla greek yogurt. So delicious and fills you up for the morning. This also makes a great afternoon snack.

Whole grain toast with nut butter or egg, oatmeal, other cereals, fruit. Stir fry an egg with brown rice and a little onion.

I don't usually have alot of time to fix breakfast, but for lunch I love to do Tuna and cut up grapes and put in one half of a pita bread, with a little lite mayo or you may want to substitute may for vanilla yogurt. yum

I like low fat yogurt with a 1/2 serving of Grape Nuts. The creamy, crunchy texture is very satisfying.

Breakfasts:
1. High fiber cereal with some fruit and a few nuts: apples, berries, dried cherries, banana and walnuts or almonds (about 2 tbls of of dried fruits and nuts or 1 serving of fresh fruit.) My favorite ceral is the the High fiber o's from Trader joes.
2. Greek or plain yogurt with fresh fruit or frozen fruit (if using frozen fruit, just use plain yogurt. All of that water changes the texture anyway. You can approximate greek yogurt by straining regular plain yogurt (as long as it doesn't have any added thickeners) in a coffee filter lined strainer. Top with granola and/or a few nuts. The great thing about this breakfast is you can prep it for all week and grab and go when you are ready (I wait to add the granola day of)
3. English muffin with peanut butter and banana and cinnamon
4. Avocado toast (optional, with tomato). . Toast your favorite whole grain bread, mash half an avocado with salt, pepper or cayenne, and squeeze some lemon or lime.
5. Oatmeal: I like to mix mine up with plain oatmeal (steel cut is great), some dried fruit or chopped apple, 2 tbls of chopped nuts, vanilla extract, cinnamon or pumpkin pie spice and maybe a little sweetener. If you use steelcut oats, mix this up overnight and top with milk, milk substitute or water. (I use almond milk). The next morning, the cook time won't be nearly as long as cooking the steel cut oats from scratch. Depending on your preferred texture, you can add the liquid the night before.
6. Scrambled eggs on whole grain toast with mixed greens or spinach (make your eggs with a tbls of freshly grated hard cheese like parmesan or pecorino or dry jack or aged gouda.

These are my typical ones. About 4-5 days a week I have greek yogurt + fruit

Try cooking a big pot of steel cut oats (usually available for under $2 a lb in the bulk food section of the grocery store) in only water and portion them out in the fridge. Nuke them with your favorite toppings each morning. I like mixing in a little plain canned pumpkin puree, cinnamon and splenda... delicious, filling and nutritious
