I use a lot of hot sauce, soy ginger to flavor stir fires/meats; wondering what else people use that's relatively healthy and quick
The best way to get the most flavor out of meat or poultry is to brown it well and then make a simple pan sauce.https://www.bonappetit.com/test-kitchen/how-to/article/perfect-pan-sauce
In general, people in the West tend to not think of adding umami flavors to food. Ketchup, soy or Worcestershire sauce, and mushrooms all have a lot of umami flavor. Yeast flakes or cans of grated Parmesan cheese are other ingredients that can be added to all sorts of dishes just for the umami element.
If you want to add heat to a dish, might as well use chili-garlic sauce. It's not just for Asian cuisine.
