Help! Dinner disaster relationship issue

My boyfriend and I have been living together for 2 years, I grew up eating boxed food and simple amercian style meals, he grew up with a mom that cooked fresh Dominican style food. I love the idea of cooking dinner every night and feeding my man but I get anxiety because I feel like we eat the same thing over and over, and I know he’s unhappy. Please give me advice, tips, recipe ideas!!! It’s putting a lot of pressure on the relationship...
