Slice about half an inch from the stem of the bell peppers and cut each of them lengthwise into half.
Add the sliced peppers, crushed (with skin-on) garlic cloves and sliced beef tomatoes to a large baking tray.
Drizzle some olive oil and salt.
Mix well and let it cook in the oven for 35 minutes, by when the peppers have a lovely char and a smoky aroma. Make sure you mix everything halfway through the cooking time.
Once out of the oven, peel the roasted garlic skin and transfer everything to a high-speed blender jar.
Add red pepper flakes, chilli powder, lime juice, fresh clove of garlic, about a tablespoon of olive oil and blend everything.
Adjust the seasoning by adding more salt, chilli powder or lime juice if necessary.
Enjoy!

Notes
Nutrition values are a rough estimate for guidance.
I prefer blending the roasted red peppers with their skin on, in a high-speed blender. This adds a lovely smoky flavour to the sauce while still retaining the smooth and creamy texture. If you do not like the skin, you may want to peel it off before blending.
