Bring a pot of salted water to a boil over medium-high heat. Crush garlic slightly with the bottom of a pan. Blanch garlic to soften and remove bitterness – approximately 4-5 minutes. Remove from water and reserve. Place beans in same boiling, salted water and blanch until bright green – approximately 3 minutes. Remove beans from water and drain well.
While beans are draining, combine sugar, Cajun spice, cumin, curry, turmeric, thyme, basil, salt, and pepper in a small bowl. Reserve.
Heat a large skillet over medium-high heat. Add oil, garlic, and roasted peppers to the pan and cook until garlic is golden brown – approximately 5 minutes. Add beans and spice mixture to the pan. Stir to combine, and continue to cook until beans are done to your liking – approximately 4-7 minutes.
