What foods can vegetarians eat WHILE earning or maintaining ripped abs?

I became a vegetarian and replaced grilled chicken and salmon with plant-based meat. Yet, plant based meat is twice the price of regular meat :(  I realized this and attempted having, instead of real meat or fake meat, other sources that do whatever "meats" (real or fake) do.  A book called "Men's Health: Getting Abs", does not recommend such substitution for protein sources.

Yet, it has a list of dairies, starches & grains, nuts and fats, and fruits.  (And unlimited raw vegetables).  To not feel really hungry a lot, I would double up on its (limited) recommended amounts of each category per day.  

Dairies such as- cheese, cottage cheese, milk, plain low fat yogurt, or  sour cream.  Starches and grains such as- beans (black, cannellini, or garbanzo), (specific) cold cereal, oats, fist sized potato, pasta, pita bread, or tortilla.  Nuts + fats such as almond butter, cashew butter, or peanut butter.  I'd normally only have a couple or few pieces of fruit each day, but now I'd an extra piece.

Normally, I wouldn't have most of those listed dairies, starches + grains, or nuts.  I'd select 1 or 2 from each category that are the fittest. And I'd have salmon and grilled chicken.  

I once was pretty overweight, I lost 50 pounds doing the above.  Yet, I saw a video of animal slaughter and went vegetarian. Ever since, I have not lost the excessive weight that I wanted to, after the 1st 50 pounds.  Yet, I want to not kill animals.  There must be another way to be fit.  

What is it?
