I ate yogurt and nuts in the mornings. Breads, lots of potatos. Lots of lentils which are legumes and have about the same protien per dollar and weight as chicken. I also put walnuts, peanuts, lots of other nuts and seeds, oils etc in my cooking. I cooked in bulk in a large pot. I also ate 5+ bowls a day a day. I just could not reach my calorie requirements. I did exercise everyday by going up the nearby mountain. Adding protien powder to my meals helped, but adding meat made it very easy to substantially increase my calorie intake.
