Really? How many calories are in a "bit of corn and peas"? How can you estimate the caloric value of a "turkey breast sandwich" which could have mayo or not, or could have 3 oz of turkey or 6 oz of turkey?
How many calories are in "maybe brown rice"? What is the caloric value of "sweet potato"?
When the OP says red meat, is that ground hamburger meat? Is a lean cut or is it filet mignon?
They did a study at Standford where they perpared plates of food and provided a list of ingredients. They then put these plates of food in front of nutritionists, food scientists and MDs.
None of them could accurately guess caloric content. Of course they did much better than their layperson/dieter counterparts, but still non of them were even reasonably accurate.
If it's been well established that not even people who dedicate their careers and lives to the study of nutrition sciences and who have been through 10 years of college cannot accurately guess, why do you feel so confident at doing it?
Well, anyway, there is no way to estimate calories without portion sizes. It's ridiculous.
