Help needed!!

So my husband was diagnosed with an autoimmune disease that has caused a thyroid issue and long story short he cannot eat anything with cholesterol over 2% so I've been struggling with meals to fit that bill. So far all we have eaten was baked chicken and potatoes and mac and cheese. Every meal we eat is little to no cholesterol and it's very limited. I have dropped things I like such as fast food and such because he can't eat it and I would feel bad if he does and it's saved us money but I'm struggling with what to cook. Eating the same thing gets really old 😭😭😭
