Rinse the grains and lentils in a fine sieve under running water for a few minutes.
Place them in a rice cooker (or saucepan, but you may need to add an extra half a cup of water before the grains are fully cooked, depending on how tight fitting the lid is) with 3 cups of water, and put it on to cook.
Preheat the oven to 200℃ (375℉)
Meanwhile, put the kale into a sieve (in which the sieve will be enclosed) and cover in boiling water.
Place a large frying pan over medium heat, and "fry" the capsicum and onion, adding a splash of water or stock to stop sticking. Do not allow it to get too moist. Once softened after a few minutes, add the herbs and garlic. Cook until the moisture evaporates out and the vegetables are fairly dry but not sticking to the pan.
Drain the kale, and squeeze all the water out of it with your hands - I find it easiest to do this in 3 or 4 small handfuls and set aside.
Once the grains are cooked (they should be fairly dry also), tip them into a large bowl, and tip in the contents of the frying pan. Sprinkle in the kale, breaking up any lumps, then add the nutritional yeast, tamari, tahini, lemon, zest & almonds and thoroughly mix.
Sprinkle some sesame seeds if using, into the bottom of each muffin hole, then pack the mixture firmly on top, pushing down to ensure no air pockets which will stop them coming out cleanly. Sprinkle some more sesame seeds on top.
Pop into the top of the oven for 20 minutes. Take out, allow to sit for 5 minutes, then invert the tray onto a cooling rack, making sure they all come out (you might need to loosen stubborn ones around the side with a plastic knife), and place that on top of a baking tray and then pop back in the oven for 10 minutes to crisp up the bottoms.
My mixture made 34, so you can use the tray again to use up the mixture for another 6-10 bites.
