I'm a little sad that I wasn't asked about this.

Bulking on Paleo is the epitome of a clean bulk. Remember, think calorie dense foods/sides like fried potatoes in EVCO, chicken thighs, bacon, avocados, etc. A meal of 8 oz of chicken thighs, 10oz of red potatoes in 2 Tbsp EVCO, an avocado, and a piece of fruit is well over 1200-1400kcals and is packed with nutrients.
