I haven't been on Veeky Forums in a long time, so this is probably super outdated, but there is an album of a bunch of crap like what people are posting here.

It all kind of depends on your phenotype though. Do you respond well to higher fat or higher carb or moderate both. I'm eating about 400-500g of carbs per day on a slight cut. So my snacks are like... greek yogurt and cereal, toast with some peanut butter and banana. Breakfast is typically pork shoulder bacon (shit is amazing, pretty solid macros, the stuff I get is like 14g protein and 6g fat per serving), eggs, oatmeal, toast or a waffle.
Dinner is typically something like steak or chicken with potatoes and brussel sprouts or other greens.
My girlfriend responds better to higher fat, so she eats like eggs, sausage, bacon for breakfast, grass-fed beef with greens for lunch, then typically her carbs come from like a potato or fruit.
Also, recommend making some kind of granola as a good snack food. You can get pretty creative with it and tailor it to yourself.
The one I currently have been making goes as follows
I toast some oats and mix it with some dried cranberries. Throw them on a baking sheet and spread it across.
In a crockpot I heat up chocolate peanut butter, peanut butter powder and coconut oil. I get it to about a pancake batter thickness.
Spread the base over the oats and cranberries and throw it in the freezer. Also done this in muffin trays and done them in small chunk that are shaped like cookies. Shit taste so good.
That reminds me of the Jeff Alberts cake. I've done his with the kodiak pancake mix. Then just throw on some coconut oil and honey and shit is pretty solid tasting for little to no prep time.
