I started eating a lot of chickpeas recently. Buy them dried, boil them for a couple minutes them let them soak in the water for a few hours. Then either roast them in the oven or if I'm lazy, toss them in the microwave for like 5 minutes, then add some seasoning. I snack on them between meals, or also toss them into things like soup or curry.

Also if you want a different take on ramen, boil them until they are al dente, drain the water and then stir fry with some cheap veggies or whatever.
