Method:
Heat oil over medium heat in a large skillet. Add onions and garlic and cook for 3 minutes. Add rice and saffron and continue to cook, stirring constantly, for 1 minute more. Add tomatoes and stir to break up with a large spoon. Add peppers and lima beans and cook, stirring, for 1 minute more. Add broth and bring to a boil. Boil for 2 minutes, then reduce heat to a simmer. Cover and cook for 10 minutes. Check to see if more liquid is needed to prevent sticking. If so, add about 1/4 to 1/2 cup water, then cover and cook another 5 minutes.
Stir in peas and cook until just tender and liquid is absorbed. The rice should not be over-cooked, but just slightly al dente. (If not tender enough, you may add a bit more water and continue cooking.) Serve garnished with lemon wedges.
