Wheat protein based shake - 120 calories, 25g protein
Two soy coffees - 300 calories, 16 calories.
Those 3 proteins complement the amino acid profiles of each other. I typically only aimed for around 130g, so with two protein shakes daily and those other foods I'm very close after only 1000 calories.
I also prefer real whole food over shakes as it keeps me from getting hungry as doesn’t digest as fast. Right now I eat 6 times a day and only my late afternoon snack is a shake with a rice cake, 20g almond butter and banana.
If you don't want to eat vegan food, the only excuse you need is "I'd rather eat meat 6 times per day". The vast majority of western people could eat bodybuilder vegan diets if they needed to. If it is something you're interested in then there is a TON of vegan bodybuilders. Google Nimai Delgado or Torre Washington, for example.
