Lee & Perrins sauce for red beans and rice is the secret ingredient, to me, and you can probably find low-salt or reduced-salt sausage if you think that's the secret ingredient. Try turkey kind, rather than pork? It has added spices. But pork, especially bacon, are just death-wish food if you have heart failure. Ketchup is filled with salt and hides the taste of food. Maybe start going to your local farmer's market every week? This is a great time of year. You'll find beautiful colors, an ever-changing array of fruits and vegetables that have so much more taste than even at produce stands and certainly better than in any stores, plus it's a festive atmosphere and helps support your local farmers.

There are endless videos about low-salt eating and cooking (and probably caretaking, too, since you mentioned that. Most are on YouTube, but there are probably some on Vimeo and longer ones on TEDtalks, too. There are even recipes for low-salt recipes and cooking demos. So: Next reason you can't do this, please? 😉
