For baked beans on toast, I recommend adding the following to your beans:

• paprika (1/4 - 1/2 tbsp)
• a small amount of ground pepper
• sriracha sauce (optional, amount depends on your tolerance/preference, I like to use roughly 2-3 tbsp)
• garlic powder (1/4 - 1/2 tbsp)
• soy sauce (0 - 2 tbsp)
• depending on your baked beans and if/how much soy sauce you used, add salt to taste

Feel free to experiment with the amounts and adding some other stuff, would love to hear your thoughts if you ever give it a try :)
