Cheap, healthy food ideas

So dh is wanting to eat healthier since he is going to the gym to lose weight, and since I'm pregnant I've been making fattier dishes for me to gain weight(I have a hard time doing so). So any ideas I would appreciate, my dh isn't picky he'll try anything. I usually just make him grilled chicken or fish and he's getting bored of those. Thanks 

I love veggies to dip in hummus. I know that's not a meal but its a great snack. For breakfast I'll have a greek yogurt of peanut butter on wheat toast. For lunch some sort of veggie centered dish, salads, chopped up steamed veggies. Dinner is my idc what I eat just watch my portions meal.
