In a small saucepan, combine diced Roma tomatoes, diced red bell pepper, half of the minced garlic, and extra virgin olive oil over medium heat.
Simmer the vegetable mixture for 15-20 minutes, stirring occasionally, until the liquid has evaporated and the matbucha is thick and jammy.
While the matbucha simmers, season the chicken breast evenly with smoked paprika, ground cumin, sea salt, and black pepper.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5-7 minutes per side until fully cooked and golden brown.
In a food processor, blend the rinsed chickpeas, tahini, lemon juice, and the remaining minced garlic until the hummus reaches a velvety consistency.
Slice the cooked chicken into strips and arrange on a large platter alongside the fresh hummus, the warm matbucha, and sliced cucumbers for dipping.
