Hey PB, I also use a lot of chilli BUT here are a few creamy style dressings/sauces I use. I like really simple stuff that has a bit of oomph to it but clean flavours so you can enjoy the food.
Or maybe I'm just italian
Dijon mustard is your friend (or a mix of spices as you please) ...
Mix a little dijon mustard with EVOO, fresh lemon juice, salt, finely chopped fresh herbs, add a spice if you like, some crushed garlic maybe. Whisk together until creamy.
Great on fish, chicken, salads and steamed/boiled veg.
If you want something really creamy, try doing the same but add mustard, lemon juice, to non fat or low fat greek yoghurt, season with salt and add finely chopped herbs, garlic and/or spices. Whisk until creamy and use with chicken, fish, lamb, veg, whatever.
You can add whatever seasonings you like ... moroccan/berbere/thai/italian/cajun/bbq whatever spice mix you like.
I love dukkah and sprinkle that on almost everything. gives food a nice zing and crunch too, especially veg.
I've also been using coconut amino seasoning (made by Banaban the coconut oil folks) and ponzu seasoning. These are both really good for dressings and cooking.
Hope that helps
