I also had a bypass surgery a few weeks ago, and it started with soups and protein shakes. I understand your desire to get back to an active life, especially if you were into sports. I'm also looking forward to when I can resume physical activity.
As for satisfying and filling meals, I've found that braised vegetables with chicken breast and quinoa can be a tasty and healthy choice. Additionally, fruits, low-fat yogurts, and vegetable omelets are good for variety. The key is to watch portion sizes and follow your doctor's recommendations.
