it's not a lot but for the anon talking about healthy recipes, I obviously don't know what you would consider healthy or what dietary restrictions or anything that your parents have but I made this veggie soup: https://natashaskitchen.com/easy-vegetable-soup-recipe/

For my family when my mum came home after getting her gallbladder removed because it's VERY low fat and it's become a family favorite

We all loved it from the get go when I made it true to the recipe but some changes I've made since are:

-a lot of the time I make it more or less with whatever veggies we already have but I've found that peas didn't really fit the flavor profile so I try to avoid them

-i blend the canned tomatoes, my sister has sensory issues and can't stand cooked tomato so maybe your parents would like that better as well

-as far a seasoning I almost always use garlic, onion, or season salt instead of regular salt when I cook to add a little extra flavor and, at least for this, I always add some crushed red pepper and basil. I also add a clove(about a tsp) of minced garlic with the onion at the beginning

As far as cooking in general goes I'm VERY white so adding flavor does NOT come naturally but one thing I can recommend is anytime you need to boil potatoes or pasta or anything like that where you're going to dump the water after, SEASON that water, I always put in all three of my big three salts(garlic, onion, and seasoned) and at least for potatoes I add some chicken stock.

I hope you and your parents like the soup and I'm not overstepping and I'm manifesting good, FLAVORFUL, healthy recipes find their way to you 😊🩷 (and I highly recommend this soup to everyone else too, my family range from mildly to very picky eaters and we all LOVE this stuff and it's relatively simple too)
