Starving all the time

Recommendations on foods that will keep me satiated while breastfeeding? My son is 12 weeks and I am always hungry. Bonus if i can fix and or eat it with one hand. I am starting to be lightheaded a lot but I try and drink lots of fluids and I feel like I eat constantly but am still hungry. I always take my vitamins and I've tried extra protein like eggs and cheese, oatmeal which is usually filling but isn't right now, hot liquids once that is supposed to make you feel fuller longer...nothing helps. It is worse when he is having a growth spurt but even when he isnt the hunger is constant. My hubby is a big guy and I've been out eating him. My weight is staying steady (sigh. You'd think I'd lose something being hungry all the time...but no luck). Help!
